Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

Question

### Problem Statement

In the figure, rigid bar ABC is supported by a pin at B and by post (1) at A. However, there is a gap of \( \Delta = 7 \, \text{mm} \) between the rigid bar at A and post (1). After load \( P \) is applied to the rigid bar, point C moves left by 9 mm. If the length of post (1) is \( L_1 = 1.65 \, \text{m} \), what is the average normal strain that is produced in post (1)? Use dimensions of \( a = 1.45 \, \text{m} \) and \( b = 0.80 \, \text{m} \). Use the correct sign conventions for normal strain.

### Diagram Explanation

The diagram shows a rigid bar ABC:
- The bar is pivoted at point B.
- Point C is near the right end where the load \( P \) is applied horizontally to the left.
- The bar has distances \( a = 1.45 \, \text{m} \) from the pivot at B to the support at A, and \( b = 0.80 \, \text{m} \) from the pivot at B to point C.
- A post (1) is located under point A with a gap \( \Delta = 7 \, \text{mm} \).

When load \( P \) is applied:
- Point C moves to the left by 9 mm.
