Suppose you have a meter stick with two masses attached. The mass m1 is 0.60 kg and it is located at x1 = 30 cm from the left (zero) end of the meter stick. The pivot point is located at x = 45 cm. The mass of the meter stick (mms = 0.40 kg) is located at its geometric center, xms = 50 cm. The mass m2 is 0.25 kg and it is located at x2 = 80 cm from the left end of the meter stick. Calculate the net torque (in N⋅m with the proper sign) due to these three weights. Use g = 9.8 m/s2.

Question

Mass m1 exerts a force m1*g at a distance of 15 cm (0.15 m) left of pivot point. That creates a counterclockwise torque of 0.6*9.8*0.15 N-m. The mass of the meter stick exerts a gravitational force ms*g through a piint 5 cm to the right of the pivot, creating a clockwise torque. Mass m2 exerts a force m2*g that is applied 35 cm to the right of the pivot.

All you have to do is compute the three torques and add them. Treat the counterclockwise torque as negative.
