An elastic bar is 0.125in. wide into the page and has a slot over part of the length, centered between top and bottom. The bar is subjected to 200lb forces as show. Due to the deformation of the bar, the points where forces are applied separate by 0.2in. (i) Determine the elastic modulus of the material. Neglect the effect of the end portions and the effect of the transitions. (ii) What kind of material would you guess this is (rubber, plastic, metal, or diamond)? (iii) Consider two tiny elements, each 0.01 in. by 0.01 in. by 0.01 in., drawn on the bar before the forces are applied. Determine the dimensions of each element in the plane when the loads are applied. Use the modulus you found in part (i) and take the Poisson ratio v = 0.3 (v was picked at random, and may not correspond to a material with the modulus you determined).
