A manufacturer purchases subassembly G that is used in the bill of materials shown in figure 1 below , from their key supplier of those items. The annual demand for G is 1000 units per year to satisfy the market demand for the final product A., in figure 1. The unit cost of G is 40 pounds per item, while the annual holding cost is 48% of the unit cost. it costs the manufacturer 35 pounds per year to order subassemblies G, which includes quality, order placing , inbound inspection and all other administrative costs. Calculate: a.) the EOQ, b.) the numbers of orders the manufacturer should place per year c.) the total costs

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.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
