Textbook Question
Chapter 6, Problem 1RQ
What is the operating voltage of most magnetic control systems?
Expert Solution & Answer
To determine
The operating voltage of a magnetic control system.
Explanation of Solution
The power supply of most industrial motors is between 240V and 480V. For use in a magnetic control system, the voltage is stepped down to 120V using a step down transformer.
Hence, the operating voltage of a magnetic control system is 120V.

- The thin-walled open cross section shown is transmitting torque 7. The angle of twist ₁ per unit length of each leg can be determined separately using the equation 01 = 3Ti GLIC 3 where G is the shear modulus, ₁ is the angle of twist per unit length, T is torque, and L is the length of the median line. In this case, i = 1, 2, 3, and T; represents the torque in leg i. Assuming that the angle of twist per unit length for each leg is the same, show that T= Lic³ and Tmaz = G01 Cmax Consider a steel section with Tallow = 12.40 kpsi.
