Write a program that will help you select the lightest W shape from a limited group of W shapes. The beam is to be simply supported and will carry a uniformly distributed line load. Consider moment only.
You will need to create a short table of W-shape properties from which the program can make the selection. (Realworld software contains more comprehensive tables of shape properties.)
Choose a few shapes (perhaps six) from Appendix I and include nominal depth, weight, and section modulus in the table. User input for this program is to be uniformly distributed line load intensity (kips/ft), span length (ft), and yield stress (ksi).
water is delivered from a pressurized storage tank to a watering trough through 600 feet of 2 inch steel pipe. the pipe
The 12-kg uniform bar AOB is pinned to the carriage at O. The carriage is undergoing the harmonic displacement y(t) = Y sin ωt, where Y = 10 mm and ω = 2 rad/s. Calculate the steady-state angular amplitude of the bar for small amplitudes.
In the TWA Flight 800 tragedy the accident is blamed on explosion of fuel vapors in the central fuel tank. The volume of the central fuel tank is 18,000 gal. For jet fuel the energy of explosion is 18,590 Btu/lb and the molecular weight is 160.

a 20-m3 tank contains nitrogen at 23degc and 600 kpa. some nitrogen is allowed to escape until the pressure in the tank
Air enters a pipe at 25 Celsius, 100 kPa at a flow rate of 36 m3/hr. A heater on the outside of the pipe draws 8 amps at a voltage of 120 V. All the heat from the heater is transferred to the air (well insulated and wall t is small).
a hydro-electric plant uses an 85 efficient turbine-generator to produce power from a reservoir with a height of 45 m
A sphere 1 m in diameter floats half submerged in a tank of oil( Sg = 0.80). a.) What is the upward force acting on the sphere? b.) What is the minimum weight of an anchor w/ a density of 20,000 N/m^3 that will be required to submerge the sphere comp..
Suppose that we know a noninteger maximum flow in a directed network with integer arc capacities. Suggest an algorithm for converting this flow into an integer maximum flow. What is the running time of your algorithm? (Hint: Send flows along cycle..
the initial pressure of a steam turbine inlet is 162 bar. if the inlet is at the above pressure and saturated vapor
