A short reinforced concrete column is subjected to a 750 kips axial compressive load. The Moduli of elasticity of plain concrete and steel are 5.5 and 30 million psi, respectively. The cross-sectional area of the steel is 1.8% of the reinforced concrete. Considering the column is made of composite material and subjected to a load parallel to the steel rebars, calculate the following: a. the modulus of elasticity of the reinforced concrete.
b. the load carried by each of the steel and plain concrete.
c. the minimum required cross-sectional area of the column, given that the allowable compressive stress of the plain concrete is 5,500 psi and that the allowable compressive stress of plain concrete will be reached before that of steel.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
