Question: The forces acting on a rectangular steel bar are shown in figure. The dimensions of this bar are: BC=1 cm, CD=5 cm and AB=2

The forces acting on a rectangular steel bar are shown in figure.

The forces acting on a rectangular steel bar are shown in figure. The dimensions of this bar are: BC=1 cm, CD=5 cm and AB=2 cm. a) What is the total change in volume of the steel bar if its modulus of elasticity is 2,100,000 kgf/cm and Poisson's ratio is 0.25? b) What must be the magnitude of the compressive load acting in AB direction so that there will be no change in volume? P1=6000 kgf A 2 cm 1 cm D P3=60000 kgf 5|cm P2=15000 kgf
