Acompound gear train is composed of four
gears: a, b, c, and d. gear a has 120 teeth. gear
b has 12 teeth and shares a shaft with gear c,
which has 24 teeth. gear c is meshed with gear
d, the output gear. power is supplied at gear a
with 200 ft. ib of torque and is traveling at 400
rpm. with a system output of 400 ft lb, how
many teeth should gear d have?
a.720
b.900
c.480
d.256

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
