An automobile is equipped with an alarm system to indicate each of the following conditions:

(a) The key is in the ignition, the door is open, and the engine is not running
(b) the lights are on when the key is not in the ignition;
(c) The seatbelt is not fastened when the motor is running; or
(d) the door is open and the motor is running. Show the alarm logic circuit when K=1

if the key is in the ignition, D=1 if the door is open, L=1 if the lights are one, M=1 if the motor is running, and S=1 if the seat belt is not fastened.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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.
