A specimen of metal of original length 80mm and original diameter 21mm was subjected to tensile a test. The load and extension at the limit of proportionality were found to be 105,000N and 0.082mm. The yield point was at a load of 112,00ON. The maximum load before the material failed was 199,000N. The final length at failure was 91mm. Calculate: i. the stress at the limit of proportionality i. the yield stress iii. the ultimate tensile stress iv. the value of Young's Modulus V. the strain at failure
