How derive the length kf cross belt drive?
Compute the percent change n in the normal forces at A and B as compared with their "engine-off" values.
consider a top secret military power supply for arctic environment operations that will produce electrical power from
Ammonia is to be isothermally compressed in a specially designed flow turbine from 1 atm and 672 R to 50 atm. If the compression is done reversibly, compute the heat and work flows needed per lb-mole of ammonia by the following methods;
a 1 m3 rocket-propellant chamber is tilled with combustion gases at 3000 k and 7 mpa at the instant combustion ceases.
the piston of a piston-cylinder device containing gas has a mass of 60kg and a cross-section area of 0.04m. the local atmospheric pressure is 0.97bar, and the gravitational acceleration is 9.81ms. determine the pressure inside the cylinder?
an object moves with constant acceleration 4.20 ms2 and over a time interval reaches a final velocity of 12.6 ms. a if
Calculate air/fuel ratio by weight, Air /fuel ratio by volume, Weight of dry exhaust gas formed per unit of fuel and Mole of oxygen in the exhaust gas per unit weight of fuel.
Time average your result in part (b). (Just set up the expression for time average).
the cylinder-piston arrangement contains carbon dioxide at 300kpa and 200 degrees celsius and the volume 0.2m3. weight
The joint of a space frame is subjected to four member forces. Member OA lies in the x-y plane and member OB lies in the y-z plane. Assume that F = 170lb. Determine the force F1 acting in OA member required for equilibrium of the joint.
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm. Determine the stress in the 'stay' at this temperature.
consider 5 kg of air initially at 101.3 kpa and 38 c. heat is transferred to the air until the temperature reaches 260
