Been worried since last night about not understanding how the arrows in the FBD corresponds to if we are taking (x1-x2) or (x2-x1). I finally understood. Thank you so much!! This made me so happy :D

I don't get the reaction forces in M2 especially the LHS of M2. Edit - Always use the reaction force when trying to establish the equation hence the equation for the second mass is wrong. It 's opposite.

Thanks for this nice video. A question: If you have assumed that the mass M2 does not move (2:55), then why We should have Fs3 and Fd3? the spring 3 should be in rest (neither compressed nor elongated), unless it was already preloaded.

Great question. I think he said it to make understanding better, but it is not exactly correct, actually we assume that x1>x2, therefore spring is in compression. Also x1_dot > x2_dot is the assumption for damper eqns.

Do you have MATLAB code to solve this?

How are the forces on left side for mass 2 acting towards the mass? Shouldn't it be the other way?

@VikiJoker1924 Жыл бұрын

Is it because when M1 moves to the right, it compresses the k2 and d2, which causes the spring and damper to exert a force on both the sides, ie force on the left and right?

Right??? Thats what makes sense to me.
