A woman with mass 50 kg is standing on the rim of a large disk that is rotating at 0.50 rev/s about an axis through its center. The disk has mass 110kg and radius 4.0 m. Calculate the magnitude of the total angular momentum of the women-plus-disk system.
The die characteristic is Q_x = 0.0015p where p is the head pressure in psi. Determine the flight angle that maximizes the flow rate Q_x and graph it.

A cylindrical bar of a metal alloy of 1.5cm in diameter and 38cm in length is loaded in tension which produces an increase in length of 0.19cm. If its yield strength is 240 MPa, its tensile strength is 310 MPa and its elastic modulus is 110 GP, deter..
A 24.8-kg aluminium block initially at 209ºC is brought into contact with a 17-kg block of iron at 101ºC in an insulated enclosure. Determine the final equilibrium temperature and the total entropy change for this process.
If the standard material is aluminum, with kA = 200 W/m · K, and measurements reveal values of TA = 75°C and TB = 60°C at Xl for Tb = 100°C and Too = 25°C, what is the thermal conductivity kB of the test material?
