How fast is the gyroscope precessing, in units of rad/s, if the disk is spinning around the axle at 28 rev/s?
The steam enters at 300 degreeC with a velocity of 25 m/s and exits as saturated vapor at 0.05 bar with a velocity of 90 m/s. Neglecting potential energy effects, determine the inlet pressure, in bar.
You are pushing a refrigerator across the floor of your kitchen. You exert a horizontal force of 315 N for 7.1 s, during which time the refrigerator moves a distance of 3.4 m at constant velocity. (a) What is the total work (by all forces) done on
