Torque, which is a measure of the rotational force acting on an object, is significantly influenced by the angle at which the force is applied. When a force is applied at different angles relative to the lever arm (the distance from the pivot point to the point where the force is applied), the effectiveness of that force to produce torque changes.

At a right angle (90 degrees) to the lever arm, the force will create the maximum torque because it acts perpendicularly to the arm. If the angle is reduced, the torque produced by the same force decreases, as the effective component of the force acting to cause rotation becomes smaller. This relationship is mathematically expressed in the equation for torque: ( \tau = r \cdot F \cdot \sin(\theta) ), where ( r ) is the length of the lever arm, ( F ) is the force applied, and ( \theta ) is the angle between the force and the lever arm.

The other options do not directly relate to the calculation of torque. While the speed of an object and the rotations it makes can influence the overall dynamics of motion in a system, they do not affect the torque generated at a given moment. Similarly, the mass of
