Question

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

Answer 1

`\tau = 50.4Nm\\`

Step-by-step explanation:

Torque is expressed according to the formula;

`\tau = Fr\\`

F is the force exerted

r is the radius

Given

F = 180N

r = 0.280m

Required

Torque

Substitute into the formula and get torque

`\tau = 180 * 0.280\\\tau = 50.4Nm\\`

Hence the torque exerted is 50.4Nm
