The tangential force method involves finding the component of
theapplied force that is perpendicular to the displacement from
thepivot point to where the force is applied. This
perpendicularcomponent of the force is called the tangential
force.

The combination of an applied force and a friction force produces a constant total torque of 35.9 N · m on a wheel rotating about a fixed axis. The applied force acts for 6.10 s. During this time, the angular speed of the wheel increases from 0 to 9.6 rad/s. The applied force is then removed, and the wheel comes to rest in 60.9 s.
