Question
**Question:** In Figure 7.16, in which direction is the effect of F3 (torque by F3) acting on the door? - ○ clockwise - ○ counterclockwise - ○ no effect, so no direction **Explanation for Diagrams (if applicable):** In physics, torque is the rotational equivalent of linear force. It causes an object to rotate around a pivot point or axis. In the context of a door: 1. **Clockwise Torque:** This indicates a rotational motion in the direction of a clock’s hands. If F3 causes a clockwise motion, the door would rotate to the right. 2. **Counterclockwise Torque:** This suggests a rotational motion opposite to a clock’s hands. If F3 causes a counterclockwise motion, the door would rotate to the left. 3. **No Effect:** This implies that the force F3 does not cause any rotational movement of the door. The actual direction depends on the point of application of F3, its angle, and the distance from the pivot.

**Figure 7.16**: The four forces are the same strength, but they have different effects on the swinging door. The image shows a top view of a door attached to a hinge on the left side. There are four forces shown with arrows, each labeled as follows: - **\(\vec{F}_1\)**: This force is applied at the edge of the door and points directly upward, perpendicular to the door's surface. - **\(\vec{F}_2\)**: This force is applied along the edge of the door, directed to the left, parallel to the door surface. - **\(\vec{F}_3\)**: This force is applied at the middle of the door at an angle, pointing diagonally outward and upward. - **\(\vec{F}_4\)**: This force is applied directly upward, near the hinge where the door rotates. All the forces have the same magnitude but cause different rotational effects due to their different points of application and directions relative to the hinge.
