A sphere of specific gravity 7.8 is ropper into oil of specific gravity of .88 and viscoisty mu = 0.15 Pa-s. Esitmate the terminal velocity of the spehere if its dimaeter is (a) = 0.1 mm, (b) = 1.0 mm, and (c) = 10.0 mm.

What precautions should you take to prevent injuries when dealing with heavy loads?

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.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
