Question
### Problem Description:

For the crank-slider machine shown below, the collar at \( A \) is frictionless. The vertical applied force, \( P = 100 \, \text{lb} \).

#### Tasks:
a) Draw the free body diagram of each member, and show all forces, including known directions.

b) Determine the magnitude of the moment, \( M \), in order for the machine to be in equilibrium.

**Answer:** \( M = 14,000 \, \text{in lb} \).

### Diagram Explanation:

The diagram features a linkage system with the following components:

- **Collar at A**: Positioned at the leftmost part and labeled as frictionless.
- **Applied Force \( P \)**: A vertical upward force of 100 lb is applied at a distance of 5 inches from the left end of the horizontal member.
- **Member AB**: Extends horizontally for 20 inches.
- **Member CD**: Angled upward, forming a linkage with pin \( D \).
- **Moment \( M \)**: Illustrated as a curved arrow at point \( B \), 20 inches from the right end.
- **Dimensions**: Distances between points are labeled—20 inches for each segment horizontally, 15 inches vertically between point \( B \) and the horizontal axis extending from \( A \).

### Note:

To solve the problem:
- Draw free body diagrams for each member.
- Use equilibrium equations to solve for unknown forces and the moment \( M \).
