A specimen of metal of original length 125mm and original diameter 27mm was subjected to tensile a test. The load and extension at the limit of proportionality were found to be 114,500N and 0.075mm. The yield point was at a load of 147,000N. The maximum load before the material failed was 205,000N. The final length at failure was 134mm. Calculate:
i. The stress at the limit of proportionality.
ii. The yield stress.
iii. The ultimate tensile stress.
iv. The value of Young’s Modulus.
v. The strain at failure.
