1. The problem statement, all variables and given/known data In the figure above, what is the torque about the pendulum’s suspension point produced by the weight of the bob, given that the mass is 40 cm below the suspension point, measured vertically, and m = 0.50 kg ? (let g = 10 ms^-2 for easier calculations) 2. Relevant equations Torque = force x perpendicular distance to the pivot 3. The attempt at a solution I first got the components of the Weight force: And I got L using trigonometry: sin60 = 0.4/L L = 0.4/sin60 L = (4root3)/15 which is about 0.463 Now torque = F x Perpendicular distance = 5cos60 x L = 5cos60 x 0.463 = 1.15 N.m But the answer is 2 N.m in the text book!! where have I gone wrong?
