Determine the radius of the crank R and the speed n of a slider crank mechanism, used in a shaker table. It is required that the average speed of the table is 5 m/s, and the maximum absolute acceleration is 3000m/s^2. Assume ratio R/L=0.2
A vehicle of mass 1500kg and track 1.8m has a centre of mass located centrally at 1,1m above the ground. It has to travel around a bend of 56m radius to the centre of mass.
A long electric wire of radius r0 generates heat at rate of q'''. The surface is maintained at uniform temp of T0. Write heat equation and boundary conditions for steady state one dimensional conduction.
Motor M draws in the cable with an acceleration of 4 ft/s2, measured relative to the 200-lb mine car. Determine the acceleration of the car and the tension in the cable. Neglect the mass of the pulleys.
A piston-cylinder device is insulated and contains 0.005 m3 of saturated liquid water at a constant pressure of l50 kPa. An electric resistance heater inside the cylinder is now turned on, and 1800 kJ of energy is transferred to the steam.
a thin metal plate is insulated on the back and exposed to solar radiation on thenbspfront surface. the exposed surface
A vapor-compression heat pump system uses R-134a as the working fluid. The refrigerant enters the compressor at 0.24 Mpa, 0 degrees Celsius, with a volumetric flow rate of 0.6m^3/min. The compression process is adiabatic to 0.9 MPa, 60 degrees Cel..
