## Homework Statement

Three forces are applied to a wheel of radius 0.350m, as shown in the figure. One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0 angle with the radius.

a) What is the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center?

b) What is the direction of the net torque in part (A).

## The Attempt at a Solution

for the one that is perpendicular

tor = 11.9 sin 90 * .350 = 4.165

for the one that is at an angle

tor = 14.6 sin 40 * .350 = 3.28

or the one tangent

tor = 8.50 sin 90 *.350 = 2.98

4.165+3.28+2.98 = 10.42?
