2. (a) (i) Is it a true or false statement that strain can be measured experimentally? (ii) Suppose that you have a rubber tensile specimen, describe a method to accurately measure strain (in longitudinal and lateral directions) during an experiment without using a strain gauge. (b) In the figure below, L is equal to 1 m and A is equal to 100 mm. If the member deforms intothe dashed shape shown, determine the normal strains ɛAB and ɛcd on the cables.
