An S 12x40.8 of A36 steel in a building is supported as a simple beam having a span equal to 17ft 6in. and carries a uniform load equal to 1.60 klf, which includes the weight of the beam over the entire span. A) Compute the maximum fiber stress. B) If the compression flange of the beam is supported laterally only at the ends of the span, what will be the allowable compressive stress in the extreme fibers?
the pressure ratio across the compressor is 9 and the maximum temperature is 827c.the turbine and comprssor processes are adiabatic with turbine efficiency of 90% and a compressor efficiency of 85%.
Use input values of epsilon (B1), pipe radius (B2), and Reynolds number (B3) to estimate "f" and place these in the same cells . Display the final answer in a message box and round to five figures. Use a short cut key of Ctrl+g
A 1000 in diameter solid steel (p= 0.303) bar is 10.0 ft long. Under a tensile load. (a) Estimate the lateral strain experienced by the bar (b) Estimate the cross sectional dimension of the bar when under strain
If the coefficient of static friction between the cord and the fixed peg at B is fs =0.25, determine the minimum weight of the bucket that will prevent the block from sliding down the incline.
The section of the plywood in the 3rd quadrant is sawed off and the resulting piece is then glued squarely over the 4th quadrant portion of the plywood with glue of negligible weight.What are the x- and y-coordinates of the resulting center of gra..
Given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
Consider a highway section where traffic is stationary, all trucks travel at speed s and cars at speed v. If aerial surveillance revealed that trucks were a fraction p of the vehicles on a photograph
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
A town is going to upgrade its primary WWTP to a secondary plant that can meet the effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a CSTR activated sludge system for the upgrade.
Lab studies have shown that the rate constant associated with the process are as follows: k = 0.95 mg COD/mg VSS-day; Y = 0.48 mg VSS/ mg COD, half-saturation K = 85 mg COD/L; ke = 0.07 d-1.
Plot the distribution of vertical effective stress and porewater pressure with depth if the void ratio of the sand is 0.6 and the degree of saturation is 90%. Neglect pore air pressure
The gas tank of a car is filled with a nozzle that discharges gasoline at a constant flow rate. Based on unit considerations of quantities, write a relation for the filling time in terms of the volume (V ) of the tank in liters (L)
