Answer to Question #201075 in Mechanics | Relativity for karen

Question

Find the combined moment of the forces P and Q about point O. The magnitude of the forces are P = 80 lb and Q = 60 lb. 

Answer 1

Assuming forces P and Q to be in downward direction as no direction is provided

Distance of P from O = x

Distance of Q from O = y

Moment of P about O = 80x

Moment of Q about O = 60y

Combined moment = 80x + 60y
