### Control Systems Objectives Part 01

**01 .** If torsional spring stiffness and reciprocal of capacitance are considered as analogous quantities the system being considered is** torque-voltage**

**02 .** Which of the following quantities under mechanical rotational system and electrical system are not analogous**? Moment of inertia-conductance.**

**03 .** The inverse Laplace transform of **1s+3 is e-3t**

**04 .** When analogy is drawn between electrical systems and thermal systems, current is considered analogous to** heat flow rate.**

**05 . ** For system shown in Fig. 18 (a) the analogous system is represented in Fig 18 (b) by **figure A.**

**06 .** The Laplace transform of damped sine wave e-at sinκt** is κ(π+π)π+κπ .**

**07 .** Under thermal and electrical system analogy, temperature is considered analogous to **voltage.**

**08 . **Mass in mechanical translational system is analogous to **moment of inertia **under mechanical rotational system.

**15 . ** The inverse Laplace transform of 1s(s+2) ππ ** ππ [1-e-2t]**

**16 . **It is generally preferred to draw analogies of non**-electrical systems to electrical systems because electrical systems are more easily amenable to experimental study.**

**17 . ** Under force-voltage analogy, reciprocal of capacitance is analogous to **spring stiffness.**

**18 .** The initial value of the function f(t) whose Laplace transform is F(S)=ππ¬ππ+π¬π+ππ+πwill be **zero.**
