Texas Instruments designed a switching power converter to have efficiency of 95% when output load is 100 W. The efficiency increases linearly up to 97% with 200 W output (i. e. efficiency is 96% at 150 W. and so on. Similarly, the efficiency decreases to 94% at 50 W output. The converter will be damaged whenever the power dissipated inside it exceeds 6 W. A) If the converter is intended to operate for output loads between 20 W and some maximum limit, what is the upper limit of output power that can safely be supplied? B) A purchaser of the designed converter by Texas Instrument finds that the efficiency is slightly worse than expected; it is 94.5% at 100 W, 96.5% at 200 W, and so on. What power limit will the user encounter?

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.
