The figure shows the cross section of a steel tube that is filled with concrete and topped with a rigid cap. Calculate the stresses in the steel and in the concrete caused by the 200-kip axial load. Use Est=29x10^6 psi and Eco=3.5x10^6 psi.
-Draw and label the diagram correctly, No diagram in the solution will be marked wrong. -Shortcut solution will be marked wrong.- Direction of the assumption of the equilibrium equation must be shown, no direction will be marked wrong.
The rigid bar AB of negligible weight is supported by a pin at 0. When the two steel
rods are attached to the ends of the bar, there is a gap D= 4 mm between the lower
end of the left rod and its pin support at C. Compute the stress in the left rod after
its lower end is attached to the support. The cross-sectional areas are 300 mm2 for
rod AC and 250 mm2 for rod BD. Use E= 200 GPa for steel.
