Problem 14PE

Suppose you exert a force of 180 N tangential to a 0.280-m-radius 75.0-kg grindstone (a solid disk). (a)What torque is exerted? (b) What is the angular acceleration assuming negligible opposing friction? (c) What is the angular acceleration if there is an opposing frictional force of 20.0 N exerted 1.50 cm from the axis?

Step-by-Step Solution:

Step-by-step solution Step 1 of 4 Take grindstone as a solid disc, from the moment of inertia of the solid disc is, Here, I is the moment o f inertia, M is the mass of the grin tone and r is the radius of grindstone. Substitute, and , Step 2 of 4 (a) Torque exerted on the grindstone is calculate from torque formula, Where the force is exerted and is the radius of the grindstone. Substitute and Hence, the torque generated is
