A 45-kg machine is placed at the end of a 1.6-m cantilever beam of elastic modulus of 200 X 109 N/m2 , cross-sectional moment of inertia 1.6 X 10-5 m4 and negligible damping. As it operates, the machine produces a harmonic force of magnitude 125 N. At what operating speeds will the machine’s steady-state amplitude be less than 0.2 mm?​

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

Have a greater impact on maintenance productivity than any other support group. (clo5) a)-the top management b)-inventory and purchasing c)-sub-contracting d)-cmms

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
