1.A 4 in. in diameter shaft moves through a well-oiled sleeve that is 12 in. long. The force required to move the shaft is 25 lbf, and the shaft velocity is 5 in./s. The oil-filled clearance between the shaft and the sleeve is 0.005 in. Calculate the viscosity of the lubricating oil (a Newtonian fluid).
2.Show how to find resultant vector mag and direction steps not just answer using parallelogram and triangle law, given angles are 25 and 50 degrees and α on this bolt step by step.
Vapour from the second effect is condensed at a pressure corresponding to 325 K. The heat transfer area is 10 m2 and the overall heat transfer coefficients are 3 and 2 kW/m2 in the first and second effects respectively.
A load is to be raised 20 ft by the hoisting system. Assuming Gear A is initially at rest, accelerates uniformly to a speed of 120 rpm , determine (a) the number of revolutions exected by gear A in raising the load. (b) The time required to raise ..
Five years ago, GSI, an oil services company headquartered in Texas, issued $10 million worth of 12% 30-year bond with the dividend payable quarterly. The bonds have a call date of this year if GSI decides to take advantage of it.

Employing the ideal gas model with constant specific heat ratio k, determine the temperature at the end of the process and the amounts of work and the heat transfer per unit mass in Btu/lb
With a safety factor of two on the time, determine the maximum static stress the component must sustain in order to have a service life of 10000 hours.
A single crystal of a FCC metal is oriented so that the [001] direction is parallel to an applied stress of 35.0 MPa. Calculate the resolved shear stress acting on the (111) slip plane in the [110], [0-11], [10-1] slip directions.
Fluids A and B ave specific gravities .75 and 1.00 respectively. If the mercury is used as manometer liquid determine the pressure difference between A and B
The maximum and minimum dry densities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m^3, respectively. Determine the density index of the sand.
On your first trip to Planet X you happen to take along a 165 g mass, a 40 cm long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth
