In a 60-cycle alternating electromotive force (emf), the angular velocity is 21,600° per second. What is the instantaneous voltage (e) at the end of exactly 0.04 seconds? The maximum voltage (Emax) is 580.0 volts. Round the answer to the nearest tenth volt.
Fill in the blank(s) with the appropriate word(s).

Answer the following statement true (T) or false (F)
Technician A says that when fifth wheel brackets are bolted to frame rails, the section modulus over that section of the frame is increased. Technician B says that installing inverted L-section reinforcements is preferred to L-section reinforcements because the section modulus is not affected. Who is correct?
A. Technician A B. Technician B C. Both A and B D. Neither A nor B
The roller chain number, such as a #80 corresponds to:

The diodes in the full-wave DC power supply shown in Figure P12.15 are silicon. Assume:
Io = 600 mA Vo = 50 V
Vripple = 8% = 4 V vline = 170 cos ?t V
Determine the value of the conduction angle for the diodes and the average and peak current through the diodes. The load voltage waveform is shown in Figure P12.17.
