A standard 20 deg full depth spur gear has 26 teeth and the circular pitch of 0.785 in.
Compute the working depth.

Why does a satellite in a circular orbit travels at a constant speed?

What should be the acceleration of a body in the uniform circular motion?

During a flow of 500 liters, the gage pressure is 68 kPa in the horizontal 300 mm supply line of a water turbine. A 41 kPa vacuum is measured at a 450 mm section of draft tube 2 m below the turbine. Assuming an efficiency of 85%,

b. Compute the output horsepower of the turbine.

c. Compute the input horsepower of the turbine.
