(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the x- and y- components of the force C which member BC exerts on

member ACD. The cables are wrapped securely around the two pulleys, which are

fastened together.

(Note the different diameters of the pulleys)

Problem

2. Relevant equations

The sum of moment in the systems = 0

The sum of force in Fx and Fy direction in an equilibrium condition equals zero.

Ok what I did was I differentiated each component and tried to calculate, but it didn't work. IN the attached file the question is shown.

Please Please I beg you all for help I have wasted a whole three days on it and even today I have slept for only 4 hours. Please it is due tommorow please help me.
