Question
Which of the following factors affects the magnitude of torque produced by a force?*1 pointA. Force and distance from the pivot pointB. Mass and velocityC. Friction and accelerationD. Density and volume
Solution
The magnitude of torque produced by a force is affected by the force applied and the distance from the pivot point. Therefore, the correct answer is A. Force and distance from the pivot point.
Here's why:
Torque (τ) is a measure of the force that can cause an object to rotate about an axis. It is calculated by the equation:
τ = r * F * sin(θ)
where:
- τ is the torque
- r is the distance from the pivot point (the axis of rotation)
- F is the force applied
- θ is the angle between the force vector and the lever arm
From this equation, we can see that the magnitude of the torque depends on the force applied (F) and the distance from the pivot point (r). The greater the force or the distance from the pivot point, the greater the torque.
Therefore, factors such as mass and velocity (B), friction and acceleration (C), or density and volume (D) do not directly affect the magnitude of the torque produced by a force.
