Question
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.
