Question

1. Bar ABC shown in Figure Q1 is made from plastic having modulus of elasticity, E = 4.0 GPa. The bar consists of two segments, AB and BC. The diameter of segments AB and BC are d1 = 100 mm and d2 = 60 mm, respectively. A longitudinal hole of diameter d is drilled through segment AB for one half of its length (250 mm). If the shortening (contraction) of bar ABC is limited to 8.0 mm, determine a) The deformation of segment BC b) The maximum allowable diameter d of the hole.
