I've been having trouble with the homework problem attached as an image.(adsbygoogle = window.adsbygoogle || []).push({});

I need to find the tension in the cable and the reactions at A (Ay and Ax). In previous homeworks, I've been able to find the reactions at similar points A by finding the moment about A around a few other points. Now that there is a pulley and platform involved, I'm drawing a blank.

In the book it says to find the Moment about the pulley the equilibrium equation is: (sum)Mo = T1(r) - T2(r) = 0 ... from which we get T1 = T2

This is an odd problem so the answer is in the back of the book and no matter what I do, I cannot get that answer.

I changed the mass of the boy and platform into units of Newtons as well.

Can anyone shed any light on this problem for me?

Thanks alot
