Question
Find the exerted force P that keeps the 4kg weight at its location. The static the friction coefficient between belt/rope and pulley is 0.12 and the angles of contact in Pulley A and Pulley B can be assumed 135o and 45.

Transcribed Image Text:The image depicts a mechanical system consisting of two pulleys and a weight. The system includes the following components:
1. **Pulleys**: There are two circular pulleys, labeled as A and B. Each has a radius of 150 mm.
2. **Pulley A**: Positioned on the left side. The center of the pulley is shown, with an indication of the radius measuring 150 mm.
3. **Pulley B**: Positioned to the right of pulley A, also with a radius marked as 150 mm.
4. **Distance Between Pulleys**: The horizontal distance between the centers of Pulley A and Pulley B is 400 mm.
5. **Weight**: A square-shaped block labeled "4 kg" is hanging on the left side of Pulley A. This weight is suspended by a rope wrapped over the pulleys.
6. **Force P**: An arrow labeled P is shown on the right side of pulley B, representing a force applied horizontally to the right.
This diagram illustrates the basic setup of a pulley system used to analyze the tension, mechanical advantage, or dynamics involving a known mass and applied force.
