🤓 Based on our data, we think this question is relevant for Professor Acosta & Hamlin's class at UF.
(a) Calculate net torque about pivot (make sure to convert cm → m)
τnet = τ1 + τms + τ2
= m1 g r1 + mms g rms + m2 g r2
= g( m1 (0.60 - x1) + mms (0.60 - xms) + m2 (0.60 - x2) )
(Subtracting each x from pivot means CCW torques are + and CW torques are −)
In the figure:
(a) 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.
(b) True/False -- The apparatus described in the previous question is in equilibrium.
