Question 1: Strain Energy 1.1 Two joules of strain energy is suddenly induced in a 200 mm long aluminum bar with a 40 mm square cross section, by a compressive load. Calculate the maximum instantaneous stress induced in the bar and magnitude of the suddenly applied load (E = 80 GPa). (6) ( 1.2 A 160 mm long connecting link is 50 mm diameter for a length of 100 mm and 30 mm diameter for the remaining length of 60 mm. The gradual application of the load P results in the link storing a total of 10 J of energy. Calculate the magnitude of the applied load P, the value of the stress induced in each section and the total extension. If this load had been applied suddenly but without shock or impact, what maximum instantaneous stress would have been induced in the link? (E = 200 GPa). (14) 100 mm 60 mm 1 N 30 mm 50 mm
