Question
When force P is apliced to the rigid arm BC, point B moves downward 0.2mm.
Determine the normal strain developed in wire CD: ___ mm/mm.
Calculate your answer to 4 digit place.

Transcribed Image Text:### Problem Description:
**Scenario:**
When force \( P \) is applied to the rigid arm \( BC \), the point \( B \) moves downward by 0.2 mm.
1. **Determine** the normal strain developed in wire \( CD \): ___ mm/mm.
2. **Calculate** your answer to 4 decimal places.
---
### Diagram Explanation:
The diagram shows a horizontal rigid arm \( ABC \) supported by a vertical wire \( CD \). The arm has:
- \( AB \) of length 400 mm
- \( BC \) of length 200 mm
- Point \( D \) is directly above point \( C \) with vertical distance \( CD \) of 300 mm.
Force \( P \) is applied downward at point \( B \).
**Objective:**
Compute the normal strain in the wire \( CD \) when point \( B \) moves down by 0.2 mm. The strain is calculated as the change in length divided by the original length.
