    Mass-Spring free body diagram

    Thanks. I'm still working on it but that helps. I'm a 50 something engineering masters student and this stuff is not coming back to me very easy as it's been a long time since I got my BS. Of course back then, resources like this weren't here either! Thanks!

    Mass-Spring free body diagram

    So I need to find the horizontal displacements Y1 and Y2 with Y1 the displacement on the first mass in the right direction and Y2 the displacement on the 2nd mass in the right direction. The motion is started from rest with Y(0) = [1 1] and Y'(0) = [0 0] Y(0) and Y'(0) should be vertical...

    Mass-Spring free body diagram

    I am trying to get started on a problem. I have two masses M1 = M2 and three springs all with the same constant. The weights and springs are on a frictionless table and the outer springs are attached to walls Wall ~~~Mass~~~Mass~~~Wall How do I draw the free-body diagram? I am confused...
