A test piece is cut from a brass bar and subjected to a tensile test. With a load of 6.4 kN the test piece, of diameter 11.28 mm, extends by 0.04 mm over a gauge length of 50 mm. Determine: (i) the stress, (ii) the strain, (iii) the modulus of elasticity. (b) A spacer is turned from the same bar. The spacer has a diameter of 28 mm and a length of 250 mm, both measurements being made at 20~ The temperature of the spacer is then increased to 100~ the natural expansion being entirely prevented. Taking the coefficient of linear expansion to be 18 x 10-6/~ determine: (i) the stress in the spacer, (ii) the compressive load on the spacer. rC.G.] [64 MN/m 2, 0.0008, 80 GN/m 2, 115.2 MN/m 2, 71 kN.] Could you please answer the parts after the first three? If you use * could you please explain what you mean by it! Thank You :)
