A steel pipe column with outside diameter 6.5 in and its wall thickness 0.25 in, supports a load of 4.45 kN. The steel pipe rests on a square steel base plate, this base plate is resting on a concrete slab as illustrated in the attached figure. 1-Determine the bearing stress between the steel pipe and the steel plate. 2-If the bearing stress of the steel plate on the concrete slab must be limited to 90 psi, what is the minimum allowable plate dimension (a)?

A steel pipe column with outside diameter 6.5 in and its wall thickness 0.25 in,
supports a load of 4.45 kN. The steel pipe rests on a square steel base plate, this
base plate is resting on a concrete slab as illustrated in the attached figure.
1-Determine the bearing stress between the steel pipe and the steel plate.
2-If the bearing stress of the steel plate on the concrete slab must be limited to 90 psi,
what is the minimum allowable plate dimension (a)?
3-Determine the average shear stress in the steel plate, explain?
Square steel-
