Consider the brass alloy the stress-strain behavior . A cylindrical specimen of this alloy 24 mm in diameter and 186 mm long is to be pulled in tension. Calculate the force necessary to cause a 0.0119 mm reduction in diameter. Assume a value of 0.33 for Poisson's ratio.
Make a form tool for lathe for making a convex groove of 3 mm radius. tool material will be tungsten carbide. Know the dimensions of tool.
A pitching wedge a golfer is using gives the ball a initial angle of 50 degrees, what range of velocities (Vo) will cause the ball to land within 3 ft of the hole?
what is the cooling temperature range obtained by thermoelectric refrigeration?
the manometer shown above in problem 1 above contains water and kerosene. with both tubes open to the atmosphere, the free surface elevations differ by H=20mm determine the elevation difference when a pressure of 98.0 Pa is applied to the right.
How can be determined the dynamic parameters of a second order system, wiht an Inertia (M), a dampening coeficient ( C ) and a Stiffness constant ( K).
Water flows at a rate of 20 l/s through a horz pipe dia .03 m. The pressure drop across the valve in the pipe is measured to be 2 kPa. Determine the irreversible head loss of the valve, and the useful pumping power needed to overcome the resulting..

Product and Engineering Design Review
Evaluate thermal efficiency of the cycle
Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4 kJ/kg. Determine (a) the fraction of heat transferred at constant volume and (b) the thermal efficiency of the cycle.
In a refrigerator 1 kW is removed from the -10 degree C cold space and 1.3 kW is moved into the 30 degree C warm space. Find the exergy fluxes including direction associated with the two heat transfers.
