A torsion bar is required as part of a suspension system for Heavy Goods Vehicle. The company assembling the system have found a new supplier and have asked for a batch of 10,000 units to be supplied. You have been sent a sample of the supply and have been assigned to investigate if they are within tolerance and comply the product specification. The testing lab has provided results for a torsion test as detailed below. Unfortunately, there appears to be a mix up and doubt has risen concerning the results. The testing equipment used for the test requires a sample to be % inch in diameter and 6 inches in length. The task is to establish if the results are for the torsion bar material. (i) Plot a suitable graph for the results detailed below. (You may need to convert units.) (ii) Establish the Modulus of rigidity of the sample material. Explain if the material is that of the torsion bar.
