Find the net torque on the wheel in the figure below about the axle through O, taking a = 13.0 cm and b = 31.0 cm. (Assume that the positive direction is counterclockwise.)
The Attempt at a Solution
just sum all for torque, I thought you could just go
τ1=9.0N ⋅ 0.31m = 2.79 n⋅m
τ2=10.0N⋅0.31 = 3.1 N⋅ m
but the torque component with the angle shown, I calculated it the same and then summed all the values of torque together, and it said it was wrong, so im assuming that you have to add something like a cosine or sine into that component because it isnt in a horizontal or vertical direction but 150° below the horizontal (positive x axis) any tips on how to solve this,????
