Answer to Problem 2STP

The correct option is (A).

Explanation of Solution

Given:

The force exerted on the lever is F=60N .

The length of the lever is l=1.0m .

The angle between the force and the perpendicular to the lever is θ=30° .

Formula used:

The torque is the product of the lever arm and the applied force.

Consider a force F is applied at the end of the lever at an angle θ with the perpendicular to the lever.

The expression for the torque is,

  τ=Flsinθ

Calculation:

The forces acting on the lever as shown in the figure below.

  Glencoe Physics: Principles and Problems, Student Edition, Chapter 8, Problem 2STP

The torque applied on the lever is,

  τ=Flsinθτ=60N×(1m)sin(30°)τ=30Nm

Conclusion:

Therefore, the torque applied on the lever is represented by option (A).
