A circular cone with semi-angle α is fixed with its axis of symmetry vertical and its vertex O upwards. A second circular cone has semi-vertical angle (π/2)-α and has its vertex fixed at O.
The second cone rolls on the first cone so that its axis of symmetry precesses around the upward vertical with angular speed λ. Find the angular speed of the rolling cone.
The gravitational acceleration also changes with altitude as g(z) = g0/(1 + z/6,370,320)2where g0= 9.807 m/s2and z is the elevation from sea level in m. Obtain a relation for the variation of pressure in the troposphere

a truck is traveling on a level road at a speed of 60 mih when its brakes are applied to slow it down to 20 mih. an
Assuming dynamically similar conditions between those of the laboratory and the projected design determine, for the "cold" test, the equivalent mass flow rate and the speed of rotation. Assume the gas properties are the same as for air
Consider a refrigerator that accepts 15 kW of heat in the evaporator and rejects 19.76 kW of heat from the condenser. The compressor requires an input of 5 kW of power and loses 0.24 kW of heat. Determine the coefficient of performance for this refri..
