Question
**Truss Force Analysis and Plotting**

**Problem 6.C1**

**Objective:**  
Determine the force in each member of the truss as a function of the dimension \( a \).

**Parameters:**  
- Plot the force in each member for \( 40 \, \text{in.} \le a \le 240 \, \text{in.} \).
- Tensile forces are plotted as positive and compressive forces as negative.

**Diagram Explanation:**

The diagram shows a triangular truss ABC. The members are arranged as follows:
- \( AB \) and \( BC \) are the diagonal members.
- \( AC \) is the horizontal member.

**Dimensions:**
- Distance from point A vertically to B is 50 inches.
- Distance from point B vertically to C is 160 inches.
- The horizontal distance from support at A to B is marked as \( a \).

**Loading:**
- There is a downward load of 25 kips acting at point B.

**Support:**
- The truss is supported horizontally and vertically at point A and vertically at point C.

The task is to calculate the forces in each member (AB, BC, and AC) while varying the dimension \( a \) within the given range, and to plot these forces considering their nature (tensile or compressive).
