Ahelical gear has 30 teeth and a pitch diameter of 280 mm. gear module is 8 and pressure angle normal to tooth is 20°. the force normal to the tooth surface is 4500 n. determine the kw transmitted at 620 rpm.

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
