Calculate the net torque about point ?O? for the two forces applied as in ?Fig. E10.2?. The rod and both forces are in the plane of the page.

Solution 2E Step 1: Torque is given by = F * l Where l = r sin Here we have to add two torques to calculate net torque. Step 2: Let counter-clockwise torque will be positive. = F l 1 1* 1 1 (8.0 N) (5*0 m) = 40.0 N/m 2 + F 2* l2 0 2 (12.0 N)(2.0 m) sin(30 ) 2 12.0 N/m
