Given the situation in the figure. The mass m1 is 0.70 kg and it is located at x1 = 25 cm. The pivot point is represented by the solid triangle located at x = 60 cm. The mass of the meter stick (mms = 0.40 kg) is located at its geometric center, xms = 50 cm. The mass m2 is 0.34 kg and it is located at x2 = 85 cm. Calculate the net torque about the pivot (in N⋅m with the proper sign) due to these three weights. Use g = 9.79 m/s2. Do not include units with the answer.
