1. The ramp is used as passengers board a small com- A muter airplane. The total mass of the ramp and six passengers is 750 kg with mass center at G. Determine the force in the hydraulic cylinder AB and the magnitude of the pin reaction at C.
2. Determine the cutting force F applied by the blade DE to the bar at G in terms of the force P applied to the handle of the heavy-duty cutter. Assume that the cutting force F is perpendicular to the lower edge of the blade DE.
A refrigerator is maintained at 5°C by removing heat from the refrigerated space at 18,000 kJ/hr. The power input to the refrigerator is 1500 W and the surrounding air is at 36° C.

If have to do a material selection case study for a rice cooker outer body where can I find the necessary requirement specifications of the material?
Steam is produced at 70 bar and some unknown temperature. A small amount of steam is bled off just before entering a turbine and goes through an adiabatic throttling valve to atmospheric pressure. The temperature of the steam exiting the throttling v..
a reversible power cycle operates between a reservoir at temperature th and a lower temperature reservoir at 290 k. at
A large explosion occurs on the earth's surface producing a shock wave that travels radially outward. At a particular location, the Mach number of the wave is 2.0. Determine the induced velocity behind the shock wave. Assume standard conditions.
An air compressor is designed to compress ambient (assumed to be 100 kPa, 20C) to a pressure 1 MPa. The heat transfer rate to the ambient is anticipated to be equal to 10% of the power input to the compressor.
Saturated liquid steam at 2 MPa steadily enters a valve where it is throttled to 0.3 MPa. The inlet and outlet diameter is 1 cm. The flow rate is 0.012 kg/s. Determine the outlet density [kg/m3] of the steam. Also show that it is reasonable to neglec..
a ball is tossed from an upper-story window of a building. the ball is given an initial velocity of 8.20 ms at an angle
