Question 2 Two brass rods, both 300 mm long are each subjected to axial load which produced a maximum stress of 180 MPa. One rod has a constant diameter of 25 mm for the whole of its length, while the other is 30 mm diameter for 100 mm of its length and 50 mm diameter for the remaining 200 mm. For brass, E = 100 GPa. | Calculate, (1) 200 mm ★ (2) 100 mm +|+ 2.1 The maximum axial load. 2.2 The strain energy absorbed by the bar. 2.3 The actual load applied. (3) 300 mm

Two brass rods, both 300 mm long are each subjected to axial load which produced a maximum
stress of 180 MPa. One rod has a constant diameter of 25 mm for the whole of its length, while
the other is 30 mm diameter for 100 mm of its length and 50 mm diameter for the remaining 200
mm. For brass, E = 100 GPa.
