[bionut]

(Q) What torque is applied to a steering wheel of an automobile when the driver applies a force of 50 Newtons tangent to the circumference of the wheel? Diameter of the steering wheel is 40 cm.

F = 50 N
D (torque arm) = 0.40m

T= Fd = 20 N... but its wrong... any ideas...

Diameter is not radius.
