Choosing any value of K obtained in (a), prove that the closed-loop system is capable of tracking a reference input r(t) = cos (√3t) with zero steady state error. (Hint: Calculate the steady state error using the FVT.)

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?

Mention two examples each of the direct and indirect measurement of force.
