A gas is contained in a vertical cylinder fitted with a piston. Atmospheric pressure outside is 1 bar, and the piston area is 10 in^2. What is the mass of the piston, if the gas pressure inside is 17 lbf/in^2? Assume standard gravitational acceleration.
consider a magnet moving in a coil of n turns. this system can be modelled as mass spring damper system. the damping
a cylindrical wheel billet 1ft. in diameter and 3ft. long initially at 1000 f is quenched in oil. assume that the
Use calculus to obtain a closed-form solution for the case where the parachutist jumper is initially at rest (v=0 at t=0) to solve F(upward)= -cv^2, where c = a second-order drag coefficient (kg/m).
calculate the force required in direct extrusion of 1100-o aluminum from a diameternbspof 6 in. to 2 in. assume that
The system is at rest in the position shown, with the 12-lb collar A resting on the spring (k = 20 lb/ft), when a constant 30-lb force is applied to the cable. What is the velocity of the collar when it has risen 1 ft? The collar is attached to th..
suppose that you have a basin of 35c warm water that you use to run a heat engine that cools its substance with air at
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
What load P allow can be supported at the midpoint of the bar if the yield stress in the steel wires is 220 MPa and in the aluminium wire is 80 MPa? A saftey factor of n = 2 is needed.
a shaft is subjected to bending and torsion such that the bending stress on the surface is 80 mpa and the shear stress
a curved nozzle assembly that discharges water to the atmosphere is shown. The nozzle mass is 4.5 kg and its internal volume is 0.002 m^3. The fluid is water. determine the reaction force exerted by the nozzle on the coupling to the inlet pipe.
two reversible refrigeration cycles operate in series. the first cycle receives energy by heat transfer from a cold
