2/20 Determine the scalar components Ra and Rb of the force R along the nonrectangular axes a and b. Also determine the orthogonal projection Pa of R onto axis a.
Find: Determine the acceleration of P - Write your answer as a vector in terms of its x-y components. Use the following parameters in your analysis: x = 2 ft, ?x = -10 ft/s and ¨x = 0
Calculate the minimum natural frequency of a hydraulic cylinder (L = 25 cm) and (D = 4 cm) connected to a 45 kg load when the hydraulic fluid is an oil with B= 1.7 GPa
a 115-v shunt motor develops 21 ib-ft when the armature current is 12 a. as the load on the motor is increased the
when a potential difference of 144 v is applied to the plates of an air-filled parallel-plate capacitor the plates
a steam turbine has extractions to provide heating steam for the feedwater heaters in a power plant. the following
Air moving at 0.3 m/s blows over the top of a chest type freezer. The top of the freezer measures 0.9 m by 1.5m and is poorly insulated so that the surface remains at 10ºC. if the temperature of air is 30 ºC , make calculations for the maximum hea..
Consider a hypothetical metal that has a hexagonal close-packed crystal structure and an atomic weight of 70.28 g/mol. If the atomic radius is 0.1473 nm and the c/a ratio is 1.723, then calculate (a) the unit cell volume, and (b) the density of the m..
in an actual refrigeration cycle using r-12 as the working fluid the refrigerant flow rate is 0.05 kgs. vapor enters
A helical spring is to be constructed from a 4340 steel. The design calls for 5 coils, a coil-to-coil diameter of 12 mm, and a wire diameter of 3 mm. Furthermore, a maximum total deflection of 5.0 mm is possible without any plastic deformation..
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.
Saturated liquid water at 25°C is pumped to a pressure of 5MPa in an isothermal process. The specific work required by the pump to pressurize the water to 5MPa can be found as the change in enthalpy of the water from the inlet pressure to the outlet ..
