A tensile test is carried out on a bar of mild steel of diameter 2cm. The

bar yields under load 80kN. It reaches a maximum load of 150kN, and

breaks finally at a load of 70kN

Estimate:

1. The tensile stress at the yield point

2. The ultimate tensile stress

3. The average stress at the breaking point, if the diameter of the
