Question

if the load p on the beam causes the end c to be displaced 4 mm downward, determine the normal strain developed in wire ce .

Answer 1

Step-by-step explanation:

The normal strain in wire CE is calculated using Hooke's law as follows:

Strain = (P × L) / (A × E)

Where:

P = Load (N)

L = Length of wire (m)

A = Cross-sectional area of wire (m2)

E = Young's modulus (N/m2)

Therefore, the normal strain in wire CE is:

Strain = (P × L) / (A × E) = (P × 0.4) / (A × E) = (4N × 0.4m) / (A × 200GPa) = 0.0008/A (N/m2)
