Hello, I need help. I do not know what to give values of the geometrical tolerance for Concentricity. They are two parts connected by a pin. Both parts are moving relative to each. Thanks for any advice.

I can not even imagine how I will it work with one bearing. I'm thinking of still the shaft deflection.

I thought of something else. Probably do not speak English so well, to explain what I want. But thank you anyway for your reply. My professor changed his mind and wants to use a different solution. He decided to use only one large bearing. What do you say?

I apologize for my bad English. It's not my native language. I do not want to deflect the shaft axis. I want the shaft axis is perpendicular to the base. I want to know whether it can deflect the shaft axis? Inasmuch as the bearings have the clearances. I mean as follows: The shaft with...

Yes, I understand, are all external conditions for the deployment of the shaft bearings. But I would like to know how to deflect the shaft mounted between two bearings, bearing me the simple radial play, axial play, free angle of misalignment. . For example as shown in fig.

and when we consider that the bearings are stored perfect, perpendicularity of shaft is also perfect. And we will consider only the will, which is in the bearing.

Hello, I want to ask if the shaft is mounted on bearings, it is possible that the shaft can misalignment? Since the bearings have "free angle of misalignment". As such it then misalignment determine or calculate? For every answer thank you in advance.

I really advise anyone knows a book or website solution for the inverse kinematics of a manipulator?

Hello, I would like to learn how to calculate and simulate in Matlab inverse kinematics of manipulators.Can you please advise me some good websites or books. I am a beginner. Thanks for any advice.

I do not understand it, to me you ask? Some will not understand it? Because I need to know what is the ratio of the masses.

Hi tiny-tim, These two bodies are connected by linear actuators. Force F of the linear actuator, will act on both the bodies. We know that the bodies should move along the path L, L=x1(t1)+x2(t1). We know that m1<m2. If I assume correctly, and the trajectory of bodies depends on the mass...

Homework Statement Two body move apart by force. Frictional forces are considering. How to calculate the ratio of weight? m1<m2 Ft1=k*g*m1 Ft2=k*g*m2 Homework Equations v1(t1)=\frac{F_{t1}-F}{m_{1}}*t_{1} x1(t1)=\frac{F_{t1}-F}{m_{1}}*\frac{t^{2}_{1}}{2}...
