Torque Rotational Motion

Question

A water wheel at a mill has a

radius of 4.97 m, and generates

4530 N*m of torque.

If the water

pushes tangent to the edge,

how much force does it exert on

the wheel?

Answer 1

Hi Mal I.,

Torque is defined and calculated as T = F * r where F is the force and r is the radius to the axis of rotation (the center of the mill-wheel). You have T and r, you just need to calculate F. That's an equation in 3 variables of which you have values for 2. That's ALWAYS soluble, isn't it??
