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

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
