Consider a causal, lti, second-order system, with transfer function h(s). since the system is second-order, the denominator polynomial of h(s) is of degree 2. for each part below, give a corresponding system transfer function and specify the locations of the poles and zeros. note the answers are not unique. the system is bibo stable, and its zero-input response is a decaying sinusoid. the system is not bibo stable. the system is bibo stable, and the zero-input response does not contain a sinusoidal term. the system's zero-input response contains a pure (i. e., the amplitude of the sinusoid is neither increasing nor decreasing) sinusoidal term.

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.
