Unformatted text preview: The linear machine shown in the above figure has the following characteristics: B = 0.5 T into page, R=0.5 Ω, l = 1m, V B =100V. At t=0, close the switch. (1)What is the steady state velocity at no load? How much is the current at steady state? (2)Suppose there is a 50N force pointing to the left from the load. What’s the steady state velocity? How much is the current at steady state? (3)Suppose a 100N force pointing to the right is applied to the bar. There is also a 50N force pointing to the left from the load. What’s the steady state velocity? How much is the current at steady state? Answer: 1 (1) (2) 2 (1) (2) 3 (1) (2) (3) MatLab Program (Optional for partial credits)...
