14 (bonus). You have a material of a length of 10mm and a diameter of 0.2 mm. When you apply a tensile 4 force of 1.1*10 N, this material elongates to the length of 15mm. You measure a diameter of the elongated sample and you find that it is now 0.16 mm. Assuming the deformation remains elastic, calculate Poisson ratio and Young’s modulus of this material (in GPa)14 (bonus). You have a material of a length of 10mm and a diameter of 0.2 mm.

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.
