An Industrial water shutoff valve is designed to operate with 30lbs of force and will encounter 200lbs of resistance force applied to a 1.5in diameter axle. What is the required actual mechanical advantage of the system?
the composite beam shown is fabricated by connecting two w6 x 20 rolled-steel members using bolts of 58-in. diameter
water is the working fluid in a vapor power cycle. the pressure and temperature at the turbine inlet are 1600 psia and
Figure 5.19 shows a pump partially submerged in oil (sg = 0.90) and supported by springs. If the total weight of the pump is 14.6 lb and the submerged volume is 40 in3, calculate the supporting force exerted by the springs.
Certain changes in joint configuration are usually made to improve the strength of brazed joints. What are some of these changes?
Find the response of systems governed by the following equation of motion for the initial conditions x(0)=1, xdot(0)=-1:
In the branched pipe system shown in Fig. 12.8, 850 L/min of water at 10°C is flowing in a DN 100 Schedule 40 pipe at A. The flow splits into two DN 50 Schedule 40 pipes as shown and then rejoins at B.
a liquid film is suspended on a rectangular wire frame. the length of the movable wire is 2 in. and the other dimension
Saturated isobutane vapor at 320 K is contained in a piston-cylinder assembly. It is expanded to 3 bar by a reversible isothermal process. At 320 K, the vapor pressure of isobutane is 6.243 bar. Using the truncated virial equation of state, i.e. with..
Calculate the force required in direct extrusion of 1100-O aluminum from a diameter of 6 in. to 2 in. Assume that the redundant work is 30% of the ideal work of deformation, and the friction work is 25% of the total work of deformation.
Use the well-ordering principle for the integers to prove the existence part of the unique factorization of integers theorem: Every integer greater than 1 is either prime or a product of prime numbers.
Express the bernoulli equation in terms of pressure, head and energy in English units then in SI units with the appropriate constant and conversions factors. use algebraic ubit equations to verify that the equation is correct.
