A 14-in. square concrete post is 6ft tall and reinforced by nine 3/4" diameter steel rods. Assume that the materials are high-strength concrete and ASTM-A36 structural steel.
a.) If a compressive load of 250,000lbs is applied to this column, find the stress in the steel and the stress in the concrete.
b.) Find the total axial deformation (strain) of the column.
Calculate the relative velocity of a solute front that is flowing through an aquifer. The organic carbon partitioning coefficient (Koc) is 6 mL/g and the friction of organic carbon in the soil is 2%.
A particle which moves with curvilinear motion has coordinates in meters which vary with time t in seconds according to x = 3.3t2 + 3.1t - 5.3 and y = 5.1t - 4.0. Determine the coordinates of the center of curvature C at time t = 1.9 s.
The torsional assembly consists of a solid bronze [G = 49 GPa] segment (1) with diameter d1 = 90 mm securely connected at flange B to solid stainless steel [G = 89 GPa] segments (2) and (3), with diameter d = 100 mm.
