High school physical wheel problem. If you understand it, you will definitely add 30 points immediat

If the B wheel is smooth and there is no friction, then B will not move, and the belt will rotate clockwise, that is, the belt will move downward relative to the B wheel at point N, so the belt will be rubbed upward at point N. The emphasis here is not "the friction on the N point on the B wheel is upward", but "the friction on the belt at the N point is upward".

The frictional force experienced at point n on the B-wheel is downward. (not up).

Analysis: A is the driving wheel, which drives the belt to move, so that the belt can move in a clockwise direction; B driven wheel (non-powered wheel), it is driven by the belt, the belt at point B moves downward, thereby driving the wheel B to rotate clockwise, that is, the wheel B rotates clockwise because the belt has a downward static friction force at point B.

The driving wheel of A turns downwards clockwise, causing the transmission belt to also pass down clockwise, while B causes B to move downward due to a motion of the rotating belt, and according to the motion analysis, the friction of the transmission belt experienced by B is downward. The friction given by the transmission belt relative to B is the same.

I don't think you're right, right?

The friction at point n on the B wheel is downward, and the friction on point B on the belt is upward.

Kindness... I'm a woman. If I am pregnant, I am sure that I 100% want the child's father to be with me and be responsible for the child.

If you need money urgently, you won't use this method. She should be afraid to be interested in you. Let it go, you'll forget about a girlfriend once you've found her.

Hope it works for you.

Try to arouse your kindness to her and redouble your love for her!!

How can you be so sure that she is not because she is in love with that man, she needs so much money It is normal that she can't take it out for a while, but if she really cheats others into getting engaged to her because of money, it is very immoral, you have to find out by yourself whether she still loves you, if she is cold You are deliberate, it is difficult for ordinary women to hide their love so thoroughly, if she no longer loves you, then I hope you will quickly cut through the mess, isolate yourself from her, and slowly dilute your own feelings. If you feel that she is still really with you, your first task is to do your best to raise this money, don't be afraid to tell the family, even if your family does not support you to do this now, even if you suffer in the future, your family will forgive you, you all have children now, marriage is just around the corner, you can spare no effort to raise money for her, I am love first, you can work hard for love, it depends on your view of love and the level of trust between you.

There's nothing you can't put down. He said, "But I just can't put it down."

The monk told him to hold a teacup, and then poured hot water into it until it overflowed. The sufferer was scalded and immediately released. The monk said

There is nothing in this world that you can't let go, and when it hurts, you will naturally let go. ”

If I love that man and have a baby together, I will never marry another man, money can be obtained in many ways, but a lover is hard to find.

Make your life a little more fulfilling, and one day you will meet someone who cherishes you, and then you will find that everyone else is a floating cloud!

Since you can't come up with the money, you can only see her being happy with others. Society is like that. You have to really love him, you have to have the courage to understand? Either take out the money, take her away desperately, or just live like that. Society is made with money. Good luck.

It's very simple, let him decide, it's good if he's willing to let go of everything and be with you, and break up if he doesn't want to, that's the best.

When you find a girl you like, you will slowly forget about her, time will dilute everything, why let yourself be so miserable, or want to open it.

You can try to read the writings about Zhuangzi, I hope it will help you! (There is always a way in life, everything will pass).

It's impossible to deliberately forget, unless you have a heart of stone. Stay in a different place for a while, or do more things that make you happy and take your attention away. Either you don't care about anything, you think when you think, and time can forget everything.

Or do something with all your attention, and you'll feel fulfilled.

This kind of woman is not worth your sadness for her, you have to believe that there is always a good woman in this world who exists only for you, all you have to do is wait quietly, work hard to earn money, and take good care of yourself. What woman doesn't love a man with money and a career? Do you say yes, brother!

Talk about your children's problems? Since it is no longer possible for you, then take away that little life, and do not impose pain on the child. Alas, tangled.

I don't think you can completely forget this, go on with your life, and keep the rest in your heart. After a long time, the injury faded.

Men, always remember, don't trust women, the more women treat her, the less they will care about you! First of all, men should put their careers first! Think about how much you were wronged when you first started working and how much life pressure you are under now.

Now this woman has made this choice for the sake of money...If you are a successful man, do you still bother with these troubles? Doesn't it feel like life is so good! You have to imagine what it would be like when you were that kind of person, and that's the secret that none of the world's successful people want to say about the Law of Attraction!

Isn't the world all running around for money? You have to work hard and prove it to others! You are the king of the world!

Who cares about your past when you're successful!? Secondly, we are all men, we must learn to be ruthless, not poisonous and not husbands! Don't live in the past!

If you succeed, even ten women have it! Money is king! For this goal, I will always walk on the road of struggle! What about you?

Care more about her, don't be crying out for it or losing it.

There is only 1 way!

Falling in love with another woman will make you forget about this woman!

It's impossible to forget her, after all, she's pregnant with your child, so you can only bury her in the bottom of your heart, let it be, and let time settle everything

You're working hard to cry or divert your attention, think more about happy things, go out and walk around more, do exercise, don't think about it.

She likes you, but if you're engaged to someone else, that's certainly not what she wants. It may also be due to family reasons, her family doesn't want you to be together, so he may also pretend to be lukewarm to you in the hope that you will give up on her early and forget her, maybe he is also suffering now. You have to forget each other now, although it may be more painful for you, but this is not a choice.

If you really want to forget about her, you should participate in more other activities, such as the gym or something, it is better not to go to the bar, and it hurts the body and the mind. Enrich your life to the fullest, and it may get better soon... Forehead..

Since we don't know much about your situation, it's mostly speculation. Hope it helps you a little.

Keep yourself busy, work, study! So there will be no leisure time to think about her! Or just fall in love again so that you can forget about her.

Break up, or tell him to treat him like your other half and have a dull marriage.

Time has witnessed growth, It's been so long, why do you have to make conflicts, maybe you discuss things in the wrong way, change your mentality, and try to see things as simple as possible. In addition, I am sending you a message: compassion has no enemies, and wisdom does not cause trouble. Very philosophical, I hope it can be used.

I think love can't be forced, your own heart clearly knows that you don't love him now, you force yourself to be with him, you won't be happy.

You will meet a lot of people who love you in your life, do you have to be with someone who loves you very much? So that if you are not happy, he will not be happy.

He will not be happy if he is with you and cannot get your love.

If you've been sure that you won't have any more sparks with him, don't be together. The longer you are together, the more you hurt each other?

Let go of each other, and you have a chance to find your true one.

You're right?

Love can't be built on simple sympathy, if you don't love him, let go of each other.

That way you don't have to go against your heart every day, it's tiring, isn't it?

Maybe when you break up with him, he will find it difficult to accept, he will feel that he has paid a lot for you, but you are not moved.

You can tactfully tell him that you are very touched and grateful for his love, and you really tried to be with him, but you finally found that love never came by force, and you once loved him, but that has passed.

You can't always rely on memories of the past to support your feelings in the present.

It's a good thing for each other to be separated, and he doesn't have to worry about not getting your heart anymore.

You don't have to worry about not being able to be honest with him.

He will find a girlfriend who is more suitable for him.

As someone who would rather be lacking than abundant, I understand the pain of you pretending to force yourself. If the older people will definitely say that you are in the midst of blessings and do not know the blessings, it is not easy to find someone who is good to you, but only you know that the person who is not suitable can only make you disgusted and disgusted. I don't know how old you are, I'm selfish and hate people who force themselves anyway.

Because I think you're not happy, and he'll feel it too, so why bother? Remember that no matter what decision you make, don't regret it, don't repeat it, be firm!

This is a common problem of women, often men love women very much, but the result is that women have no direction. I think you will be happy for a lifetime with a man who loves you and feels sorry for you. If this man is not like that for you, maybe you are afraid of losing him, but you may love him very much.

This is the love that is easy to get and not cherished ... Alas... He's so pitiful...

Oh, yes. This man is very pitiful, your own original words: I found out that I didn't love him anymore, or maybe I didn't love him, and then I kept being single with an attitude of preferring to lack to excess, although I didn't love him, but I sometimes missed him, and then he came to me again, and I promised to get back together.

Since you are worried, people have changed jobs in order to prove that they love you. It turned out to be tragic that you were told ...

I don't like it at all, why are we reluctant to be together, the melons of Qiangniu are not sweet.

Talk to him, no one should be angry, he said that he didn't know because he didn't know when you would go back, he couldn't say the exact number, it was better to find someone he loved than to find someone who loved him. This is the love of reality.

If you continue, it will hurt the 、... of two peopleIt's good to make it clear as soon as possible.

You don't love him, you're just afraid of being alone. Let it go, or you'll lose a lot of your opportunities. When you find someone you really like, and then think about it now, you will feel how stupid you are at that time?

Adjust your mentality, everyone will have their own happiness, really like a person, bless him, hope he is happy. Now that he already has a family of his own, don't bother him anymore. You know, he has a woman who loves him very much, and they want to protect this family together, maybe he stayed for you, but this is all temporary.

Women, while loving themselves, must also learn to love others. So, let him have his own happiness! Don't ask for eternity, as long as you have it!

There is a lot of helplessness in life, don't care too much about others, care more about yourself, if you really can't let go, take the initiative and don't let yourself regret it

Sister, forget it if you don't contact, maybe you'll be wrong. Let's not be a junior, okay? Even if he succeeds, such a man will still have a little four!

It's very simple, forget about him, this needs you to go down and do it.

Well, it depends on your own feelings, recommend the first one, and the second one you don't know how to cherish together, you will regret it and not be happy.

Life is a good contradiction, there are gains and losses, if the purpose is to get married, you still have to objectively see whether your personality is compatible or not, two people live together, and then women still have to look at the man's ability and economic conditions, not necessarily how, can reach the basic bottom line in your heart.

In fact, loving someone does not have to be with him, and living together is not necessarily the one you love the most, as long as you have feelings. People use each other, and love is the same. There is only a material and a spiritual aspect.

It's not like there's a saying that it's better to find someone I love than to find someone who loves me, this sentence is very true... Hope you can find your own LG. Blessings...

I think two people should be together to see if their personalities and goals are suitable, otherwise they will still be separated in the future even if they are together! Your second boyfriend is quite wronged, it's because you haven't cherished it yourself, if you think about who to be with, just be single-minded and completely cut off with the other one! Wishing you happiness!
