#1

A non-uniform bar of weight W is suspended at rest by two strings of negligible weight as shown in figure. The angles made by the strings with the vertical are 36.9° and 53.1° respectively. The bar is 2 m long. Calculate the distance of the centre of gravity of the bar from its left end.


#2

Because the bar is in equilibrium state, the total resultant moment of all the forces acting on it about any point must be zero; as well as net force acting on it must be zero.
