Question

launch the simulation, then answer the question. moment of a force about a specified axis a force whose line of action does not intersect an axis (causes a moment about that axis). in this situation, the nut can only rotate around the y - axis. in the interaction, you will observe the following when the length of the wrench handle and distance to the axis are changed: 1. the right - hand rule. 2. the magnitude of the moment. part a which factor most affects torque about the y - axis? - angle from perpendicular to rotation axis length of the handle length of the axis angle of the moment provide feedback submit request answer

Explanation:

Step1: Recall torque formula

The formula for torque $\tau = rF\sin\theta$, where $r$ is the distance from the axis of rotation to the point of force - application (length of the handle in this case), $F$ is the force applied, and $\theta$ is the angle between the position - vector $r$ and the force - vector $F$ (angle perpendicular to the rotation axis).

Step2: Analyze the factors

The length of the axis is not directly related to the torque about the $y$ - axis. The angle of the moment is not a standard factor in the basic torque formula. The length of the handle ($r$) and the angle perpendicular to the rotation axis ($\theta$) are the key factors. Among them, the angle perpendicular to the rotation axis has a more direct impact as it is part of the $\sin\theta$ term in the torque formula. When $\sin\theta = 1$ (i.e., the force is applied perpendicular to the position - vector from the axis of rotation), the torque is maximized.

Answer:

angle from perpendicular to rotation axis
