Using the data below, calculate the minimum number of teeth on pinion: *remember that for teeth to round up any decimals to the nearest integer. gear type: helical. teeth: full-depth. normal pressure angle: 20. helix angle: 25.transverse pitch (teeth/in): 6.gear ratio: 5

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
