Consider two possible schemes for measuring angular velocity with an encoder. In Scheme A, a timer is set for a specified time interval TA, and the number of W/B transitions, MA, occurring in that interval are counted. In Scheme B, the time, TB, required for a fixed number MB of W/B transitions is measured.
Which of the following statements is true?
a. In scheme A, time interval TA is not the exact time that has elapsed for MA W/B transitions.
b. In scheme A, time interval TA is the exact time that has elapsed for MA W/B transitions.
c. Scheme A and scheme B, both have the same level of accuracy.
d. Scheme A is better than scheme B.
e. Scheme A is equivalent to scheme B.

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.
