Assume an object is able to rotate around a rotation axis (a pivot point). A force is applied onto the object at a distance (lever arm) from the pivot point such that a torque is produced which will rotate the object.

Given the situation described below on the left, match it with the correct statement on the right.
1: Increasing the force applied
2: Increasing the lever arm used

Question

Assume an object is able to rotate around a rotation axis (a pivot point). A force is applied onto the object at a distance (lever arm) from the pivot point such that a torque is produced which will rotate the object.

Given the situation described below on the left, match it with the correct statement on the right.
1: Increasing the force applied
2: Increasing the lever arm used

In this matching scenario, we are looking at how torque is affected by two different changes to the system.
Option: 'will increase the torque produced' — this is the right-hand statement that describes the effect on torque.
First, recall the fundamental relation for torque: τ = r × F, where τ is torque, r is the lever arm (distance from the pivot to the point where the force is applied), and F is the force applied. The magnitude of torque is proportional to both the force and the lever arm when the force is applied perpendicular to the lever arm.
Examining the left item 1: 'Increasing the force applied.' If you increase F while r remains the same, τ increases proportionally. Therefore, increasing force leads to greater torque. This aligns precisely with the statement 'will increase the torque produced.'
Examining the left item 2: 'Increasing the lever arm used.' If you increase r while F remains the same, τ also increases proportionally. Hence, increasing the lever arm also leads to greater torque. This, too, matches the statement 'will increase the torque produced.'
To address potential confusion, consider what would cause torque to decrease: reducing either the force F or the lever arm r would reduce τ, or applying force in a direction not perpendicular to the lever arm would yield a smaller effective torque due to the sine component in τ = rF sin(θ). However, the two given left items specify actions (increasing force or increasing lever arm) that increase torque, so both map to 'will increase the torque produced.'
