Asteel column with 4-in diameter supports a compressive load of 160-kips. the column rests on a 10-in by 10-in base plate with 1-in thickness, which in turn rest on a square 40-in by 40-in concrete slab with 6-in thickness. if (taiiow and tatiow in the steel are not to exceed 18-ksi and 9-ksi and in the concrete are not to exceed 3,000-psi and 1,200-psi respectively, and bearing stress on the soil be limited to 300-psi, determine whether all the dimensions given for the column, the base plate, and the concrete are adequate or not? 160-kips answers: all adequate, except plate thickness: minimum thickness t = 1.27-in
