Question

(8%) Problem 12: Suppose you exert a force of 185 N tangential to the outer edge of a 1.745-m radius 77.5-kg grindstone (which is a solid disk). A 33% Part (a) What is the torque t, in newton meters,

Answer 1

Explanation:

Take grindstone as a solid disc, from the moment of inertia of the solid disc is,

775-kg

Here, I is the moment of inertia, M is the mass of the grindstone and r is the radius of grindstone.

Substitute, and ,
