A load test on a 8-mm diameter by 375-mm long aluminium, Ask an Expert

Engineering

A load test on a 8-mm diameter by 375-mm long aluminium alloy rod found that a tension load of 4800N caused an elastic elongation of 0.52-mm in the rod. Using this result, determine the elastic elongation that would be expected for a 23-mm diameter rod of the same material if the rod were 1.2m long and subjected to a tension force of 23kN.

Part 1: Calculate the cross-sectional area of the test rod with a diameter of 8mm.

Part 2: Calculate the normal stress in the test rod with a diameter of 8mm due to the 4800N-test load.

Part 3: Calculate the normal strain in the test rod with a diameter of 8mm due to the 4800N-test load.

Part 4: Calculate the elastic modulus of the aluminium alloy. Assume the material is exhibiting elastic behaviour.

Part 5: Calculate the cross-sectional area of the rod with a diameter of 23mm.

Part 6: Calculate the normal stress in the rod with a diameter of 23mm due to the 23-kN load.

Part 7: Calculate the expected strain in the rod with a diameter of 23mm produced by the 23-kN load.

Part 8: Calculate the expected elongation in the rod with a diameter of 23mm produced by the 23-kN load.
