A bar ABC of length L consists of two parts of equal lengths butdifferent diameters. Segment AB has diameter d1= 100 mm whilesegment BC has diameter dz = 60 mm. Both segments have lengthL/2 = 0.6 m. A longitudinal hole of diameter d is drilled throughsegment AB for one-half of its length (distance L/4= 0.3 m). The baris made of plastic having modulus of elasticity E = 4.0 GPa.Compressive loads P= 110 kN act at the ends of the bar. If theshortening of the bar is limited to 8.0 mm, what is the maximumallowable diameter dmax (mm) of the hole?dmaxd24.2(a)
