A concrete column has a diameter of 360 and a length of 2.4 mm . If the density (mass//volume) of concrete is 2.45 Mg/m3Mg/m3, determine the weight of the column in pounds.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
