Question

Find the net torque on the wheel in the figure below about the axle through O perpendicular to the page, taking a = 8.00 cm and b = 22.0 cm. The total torque on an object is the sum of the individual torques. Remember that d is the perpendicular distance from the rotation axis to the line of action of the force F rightarrow, called the moment arm or lever arm of F rightarrow. We have the following. tau = Fd = +( N)(0.08 m) - (10.0 N)( m) - ( N)(0.22 m) = N middot m This represents a torque vector that points into the plane of the page, and results in a turning by the force.

Explanation / Answer

a)

= 12.0 * 0.08 - 10 * 0.220 - 9.00 * 0.22

= -3.22 N.m
