A ball is thrown vertically up with a velocity of 91 ft/sec at the edge of a 190-ft cliff. Calculate (a) the height h to which the ball rises and (b) the total time t after release for the ball to reach the bottom of the cliff. Neglect air resistance and take the downward acceleration to be 32.2 ft/sec2.
The plate is submerged in a liquid is a vertical position with the parallel sides horizontal and the shorter parallel side at the top and exactly in the surface of the liquid. The static moment of the plate with respect to the surface of the liqui..
Determine the specified data for water at the states indicated and locate each state on a P-v and T-v diagram.
Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4 kJ/kg. Determine (a) the fraction of heat transferred at constant volume and (b) the thermal efficiency of the cycle.
Determine the angle between his velocity vector and the line from his position to the airlock's position.
A wooden board AB, which is used as a temporary prop to support a small roof, exerts at point A of the roof a 57-lb force directed along BA. Determine the moment about C of that force.
Determine the number of storage bits required in the controller memory so that the accuracy of the joint is as close as possible to, but less than, its repeatability. Use six standard deviations as the measure of repeatability.
Refrigerant 134a enters a heat exchanger in a steady state refrigeration system as saturated vapor at 0 °F and exits at 20 °F with no change in pressure.
A thin electric heater is wrapped around a rod of diameter 3 cm. The heater dissipates energy uniformly at a rate of 1300 W/m. Air at 20°C flows normal to the rod with a velocity of 15.6 m/s. Determine the steady state surface temperature of the h..
