6. [20pt] Consider below source network composed of resistors and independent sources. (a) [8pt] Use the superposition properties to find the output voltage, vo. (b) [7pt] Find the Thevenin Equivalent of the circuit with respect to the terminals a and b. (c) [5pt] What is the optimal load resistance value (RL. Opt) for the maximum power transfer? And what is the maximum power (PL. Opt) that can be delivered to it?

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%?
