Consider the compression of a gas by means of a crank-piston arrangement. Let the cylinder have a single average temperature, and define thermal resistances between the gas temperature T and the cylinder temperature and between the cylinder temperature and the atmospheric temperature T0. Make a bond graph that would allow you to predict the crank torque τ for low speeds of rotation, ω. (Note that you do not have enough information to evaluate all the system parameters.)
When subjected to 1kN axial tension, bar 1 elongates by 5mm. What will be the elongation of bar 2, d2, if it is compressed axially with a load of 25kN
What load is needed to generate a transverse center displacement of 5 mm for an aluminium beam of 15 cm length, 2 cm width and 2 mm thickness (in three-point bending). Determine what strain you expect at the bottom surface for this deflection for Al ..
in a steam power plant operating on a reheat rankine cycle steam enters the hp turbine at 15 mpa and 620oc and is
What force F must be exerted by the ground on each of the main braked wheels at A and B to counteract the turning effect of the two propeller thrusts? Neglect any effects of the nose wheel C, which is turned 90° and unbraked.
a pump steadily draws water from a pond at 20 lbs. pressure at the inlet is 14.7 psi the temperature is 68 degrees f
Find the displacement of node 3 and the stresses in the two members of the truss shown in Fig. 12.25.
7.14 Consider a single crystal of nickel oriented such that a tensile stress is applied along a [001] direction. If slip occurs on a (111) plane and in a [101] direction, and is initiated at an applied tensile stress of 13.9 MPa (2020 psi), comput..
Water at 40 degrees Fahrenheit (p=62.42 lbm/ft3 and u= 3.74 lbm/ft. hr) is flowing through a 0.12 in (0.01 ft) diameter 30 ft long horizontal pipe steadily at an average velocity of 3 ft/s. Determine the head loss, pressure drop, and the pumping powe..
Compute the coordinates of the midpoint of the couple DE. Use Maple to plot the coupler curve for this point as a function of the input angle θ and calculate the mobility of the linkage
An insulated tank is divided into two parts by a partition. One part of the tank contains 2.5 kg of compressed liquid water at 60°C and 600 kPa while the other part is evacuated. The partition is now removed, and the water expands to fill the entire ..
1. For each case, determine the specified property at the indicated state. Locate the state on a sketch of the T-y diagram. (a) Water at y 5 0.5 m3/kg, p 5 3 bar, determine T, in °C.
Calculate the pBr of a bromide-containing solution that IS saturated With CuBr and contained in the cell described in (b) if the resulting potential IS -0.095 V.
