Question

ii) A force of 100N is applied tangentially to a wheel of
dimeter 0.4 m, calculate the torque about the centre of the
wheel.​

Answer 1

Given

F = 100N

r = 0.2m = 20cm

Formula

Torque τ=F×r

Calculation

Torque τ=F×r ,

where r is the perpendicular distance between the line of action of the force and the axis of the rotating wheel

= Radius of the wheel = 20 cm

τ=100×20=2000

Result

2000Nm
