A force with a given magnitude is to be applied to a wheel.The torque can be maximized by:
A)applying the force near the axle, radially outward from the axle
B)applying the force near the rim, radially outward from the axle
C)applying the force near the axle, parallel to a tangent to the wheel
D)applying the force at the rim, tangent to the rim
E)applying the force at the rim, at 45 ° to the tangent

Question

Quizplus · Accepted Answer

Torque is maximized when the force is applied at the rim (maximizing the radius of application) and tangent to the rim, ensuring the force is perpendicular to the radius, which maximizes the torque produced according to the formula τ = rFsinθ, where θ is 90 degrees in this case.
