Put four red LED as a straight line and connect each of them to a corresponding analog output. Connect a potentiometer to a 5 Volt power source. Divide the 0 to 5 Volt output of the potentiometer into four parts (0 ~ 1.25 Volt, 1.25 to 2.5 Volt, 2.5 to 3.75 volt, and 3.75 to 5 Volt). Write a program to change the brightness of a LED with respect to the voltage. For each 1.25 V interval, the brightness of one LED will be proportional to the output voltage of the connected potentiometer.

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.
