A linear power supply consists of a transformer, 4-diode bridge rectifier, smoothing capacitor, and a linear voltage regulator. The regulator has a 65 dB ripple rejection ratio. The ripple voltage across the smoothing capacitor is 350 mV. Which of the following is the best estimate of the ripple voltage across the load? a. About 0.11 HV.
b. About 200 μν.
c. About 5.4 mV
d. Need more information.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
