Questions & Step-by-Step Solutions
Which of the following statements about torque is true?
Step 1: Understand what torque is. Torque is a measure of how much a force acting on an object causes that object to rotate.
Step 2: Know the formula for torque. The formula is τ = F × d × sin(θ), where τ is torque, F is the force applied, d is the distance from the pivot point to where the force is applied, and θ is the angle between the force and the line from the pivot to the point of application.
Step 3: Recognize the importance of the angle (θ). The angle affects how effective the force is at causing rotation. If the angle is 90 degrees, sin(θ) is 1, and the torque is maximized.
Step 4: Conclude that torque does depend on the angle of application because the sine of the angle is part of the torque formula.
