Pulley example 1
To find the acceleration of the masses and the tension in the cable I recommend the following steps: 1) Draw FBD 2) Define axes 3) Apply newtons 2nd law 4) Find acceleration relationship Since we're dealing with a massless set of pulleys...

Relative acceleration (with rotating axes) Proof
If the relative axes xy aren't rotating (w=0) then the acceleration equation becomes Aa = Ab + Aa/b However, in general, relative reference axes can rotate and the following relative acceleration equation becomes Aa = Ab + Arel + Ap/b +...

Relative Motion with rotating axes example 1
The relative velocity equation for a object with rotating reference axes is: Va = Vb + Vrel + Vp/b This problem can be solved graphically by calculating lengths of the triangle that forms these vectors, or analytically by deconstructing...
