A150-lbm astronaut took his bathroom scale (a spring scale) and a beam scale (compares masses) to the moon where the local gravity is g = 5.48 ft/s^2. determine how much he will weigh (a) on the spring scale and (b) on the beam scale. the acceleration of high-speed aircraft is sometimes expressed in g’s (in multiples of the standard acceleration of gravity). determine the net upward force, in n, that a 90-kg man would experience in an aircraft whose acceleration is 6 g’s.

Fluids at rest possess no flow energy. a)- true b)- false

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
