4. 1 atm air flows at 7.5 m/s over a 1.5 m x 6 m flat plate. Air temperature is 20oC and the plate temperature is 140oC. Determine the rate of heat transfer from the plate if the air flows parallel to the 1.5 m side. If the leading edge of 0.2 m is insulated, determine the rate again and compare the two cases

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.
