Write a program that will select the required depth (2-in. increments) of a 2-in.-thick timber joist that will be spaced 16 in. on center and support a floor carrying a uniformly distributed load. Use nominal dimensions and properties. Consider moment and shear. Limits on the nominal depth are to be 6 in. minimum and 12 in. maximum. User input is to be live load (psf), dead load (psf), and span (ft). Neglect the weight of the joist.
r.c had earnings per share of 8 in year 2010 and it paid 4 dividend. book value per share at years end was 80. during
If you use more than one method, compare the respective results. Note that, in using FEHT or IHT, a look-up table must be created for prescribing the variation of the heater flux with time (see the appropriate Help section for guidance).
Calculate the percent energy distribution in a steam generator that goes into steam, losses to flue gases, refuse and heat losses. The steam generator receives 480 short tons of coal per day. The heating value of coal is 13,000 BtU/lb",. 375,000 Ib,j..
The external heat transfer coefficient is h=10 W/m^2*K. What is the rate of heat loss to the ambient?
Gasoline is unloaded from a tanker truck through a 4 inch diameter rough-surfaced hose. This is a "gravity dump" with no pump to enhance the flow rate. It is claimed that the 8800 gallon capacity truck can be unloaded in 28 minutes. Do you agree? Sup..
a fixed quantity of air at t1 100oc and p1 243 kpa is heated at constant pressure in a piston-cylinder assembly to t2
Motor coming to rest, A motor is running at 12 rpm and the switch is flipped and cuts the power. The rotor weighs 75 lbs.
Starting from rest the motorboat travels around the circular path,P = 50m , at a speed v=(0.8t)m/s, where t is in seconds. Determine the magnitude of the boat's velocity when it has traveled 40m. Determine the magnitude of the boat's acceleration ..
the rigid tank illustrated in the figure has a volume of 0.06 m3 and initially contains a two-phase liquid-vapor
If this machine works as a heat pump, how much heat will it deliver to the environment?
The gas is expanded adiabatically ( dQ = 0) and quasi-statically until its temperature falls to - 50°C. What are its imtial and final pressures and its final volume?
Oil with a specific weight of 55.0 lb /ft3 flows from A to B through the system shown in Fig. 6.35. Calculate the volume flow rate of the oil.
