6) Determine the reactions at A and B for the steel bar and loading shown in Fig. I, assuming a close fit at both supports before the loads are applied. A = 250 mm? 150 mm 30X0 KN 150 mm A = 400 mm2 150 mm K 600 kN 150 mm B 7) A steel bar 20 mm square in section is subjected to an axial compressive load of 60 kN. Find the percentage change in volume if the bar is 500 mm long. What are the equal stresses that must be applied to the sides of the bar if the volumetric change is to be zero? E = 200GPA and v=0.3.

8) Two cylindrical rods, one made of steel (E=200GPA) and the other brass (E=105GPA) are joined at C. End A of the composite rod obtained this way is fixed, while a 0.14 mm gap exists between end E and a vertical wall. A 60 kN force is then applied at B and 40 kN force at D, both horizontal and acting towards right as shown in Fig:7. Determine: i. ii, The reactions at A and E. The deflection of point C.
