A buffer amplifier with a gain of 1 V/V has an input resistance of 1M ohms and an output resistance of 20 ohms. It is connected between a 1-V, 200k ohms source and a 100 ohms load. What load voltage results? What are the corresponding voltage, current, and power gians (in dB)?

What precautions should you take to prevent injuries when dealing with heavy loads?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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.
