Question

a The following observations were made during a tensile test on mild steel specimen 40mm in diameter and 200mm long.

Elongation with 40kN load (within limit of proportionality) = 0.0304mm

Yield load = 161kN

Maximum load = 242 kN

Length of the specimen of the fracture = 249kN

Determine :

1. Young's modulus of elasticity

2. Yield point stress

3. Ultimate stress

4. Percentage elongation
