The elastic limit of brass is 379MPa . What should be the minimum diameter of a brass rod if it is to support a 400 N load without exceeding its elastic limit?

The elastic limit of brass is 379 MPa . What should be the minimum diameter of a brass rod if it is to support a 400 N load without exceeding its elastic limit ?

How much a hollow cylindrical piller of height 6m and external diameter 28cm and internal diameter 22cm will contract under a load of 60,000 kg? Given Young's modulus of the material to be 21 xx 10^(10) N //m^(2) .

Two strips of metal are riveted together at their ends by four rivets, each of diameter 6mm. What is the maximum tension that can be exterted by the riveted strip if the shearing stress on the rivet is not to exceed 6.9 xx 10^(7) Pa ? Assume that each rivet is to carry one quarter of the load .
