Question
A force of 180 N is applied tangential to a solid aluminium disk of radius 0.3 m. If the mass of the disk is 40 kg, calculate the torque exerted.
Correct Answer
Option D is the correct answer.
Detailed Explanation
Torque τ = F × r = 180 × 0.3 = 54 Nm.
Hint
τ = F × r for force perpendicular to radius.
