Acylindrical rod of copper (e = 110 gpa, 16 × 106 psi) having a yield strength of 240 mpa (35,000 psi) is to be subjected to a load of 6640 n (1493 lbf). if the length of the rod is 380 mm (14.96 what must be the diameter to allow an elongation of 0.50 mm (0.01969

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

The law of reflection states that the angle of reflection is equal to the angle of

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
