The mechanical properties of a metal may be improved by incorporating fine particles of its oxide. given that the moduli of elasticity of the metal and oxide are, respectively, 68 gpa and 380 gpa, what is the
(a) upper-bound, and
(b) lower-bound modulus of elasticity values (in gpa) for a composite that has a composition of 63 vol% of oxide particles.

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.
