Leighton industries needed steel pipe to build furnaces for a customer. leighton sent callier steel an order for a certain quantity of "a 106 grade b" steel. callier confirmed the order and created a contract by sending an invoice to leighton, stating that it would send "a 106 grade b" steel, as ordered. callier delivered the steel, and leighton built the furnaces, but they leaked badly and required rebuilding. tests demonstrated that the steel was not in fact "a 106 grade b," but an inferior steel. leighton sued. who wins?

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.
