Errors in the output voltage of an actual integrated circuit operational amplifier can be caused by : Select one:
a. Zero offset voltages and currents
b. Low open-loop voltage gain
c. High slew rate for signals which change quickly
d. All of these
e. High bandwidth for high frequency signals

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.
