In order to understand the relationship between torque, force, and distance, it's crucial to recognize that torque is defined as the product of the force applied and the distance from the pivot point at which that force acts, specifically when the force is applied at a perpendicular angle to the distance from the pivot.

Torque can be calculated using the formula:

[

\tau = r \times F \times \sin(\theta)

]

where ( \tau ) is the torque, ( r ) is the distance from the pivot point, ( F ) is the force, and ( \theta ) is the angle between the force vector and the distance vector. The maximum torque is achieved when the force is applied at a right angle, or 90 degrees, to the distance vector, because at this angle, the sine of 90 degrees equals 1.

When torque is maximized, it effectively rotates an object around the pivot. Therefore, the correct orientation for the force relative to the distance from the pivot point is at right angles, enabling effective rotational movement and torque generation.
