Compute the minimum weight of block A shown for motion to be impending down the plane. Assume the pulley to be frictionless. Block B weighs 500 lb. The coefficient of static friction for all contact surfaces is 0.20.
Determine the maximum temperature to which water can be superheated at 133 bar without boiling and the temperature to which water vapor can be sub cooled at the same pressure without condensation occurring.
Assuming that in drawing of cups, the thickness of the cup bottom and wall is the same as that of the original sheet, ?nd an expression for the ratio of the cup height to diameter, h/d1, in terms of the ratio of blank diameter to cup diameter, do/d..
when the three blocks are released from rest they accelerate with a magnitude of 0.660 ms2. block 1 has mass m block 2
Steam at 140 lbf/in.2, 1000°F enters an insulated turbine operating at steady state with a mass flow rate of 3.24 lb/s and exits at 2 lbf/in.2 Kinetic and potential energy effects are negligible. Determine the maximum theoretical power that can b..
Compute the energy loss in a 90° bend in a steel tube used for a fluid power system. The tube has a 11/4-in OD and a wall thickness of 0.083 in. The mean bend radius is 3.25 in. The flow rate of hydraulic oil is 27.5 gal /min.
