Design a cantilever beam made of reinforced concrete. The rectangular beam is 18 ft long and subjected to a uniformly distributed dead load of 1.5 kip/ft (not including the beam weight), a live load of 1.5 kip/ft, and a load of 2 kip/ft by earthquake effect. Use Fc'=5000 psi for concrete and Fy=50,000 psi for steel. Use #3 stirrups (ds=3/8 in) and #4 hangers.
the flow profile is such that u=u(max)*(1-(r/R)^2) where u is the flow speed and r is the distance from the centre of the pipe in the radial direction. What is the shear stress on the pipe wall What is the shear force exerted by the oil on a 1m lo..
The wood specimen is to be loaded in a testing machine until it fails in tension. The ultimate normal strength of the wood is ?ult = 1800 psi and the ultimate shear strength of the wood is ult = 800 psi.
A vertical triangular orifice in the wall of a reservoir has a base 0.9m long,0.6m below its vertex and 1.2 m below the water surface. Determine the theoretical discharge?
A ladder of mass 20 lbs. is leaned at an angle of 62 degrees against a smooth frictionless wall. What is the magnitude of the reaction (in lb-wt) where the ladder touches the wall?
The initial piezometric head in a confined aquifer has a thickness of 11.6 m is 85.7 m above sea level. A well with a radius of 0.5 m pumps at a constant rate of 1240 m3/day. After the cone of depression has achieved equilibrium, the piezometric head..
A vertical 12-cm diameter piston-cylinder device contains an ideal gas at the ambient conditions of 1 bar and 24oC. initially the inner face of the piston is 20 cm from the base of the cylinder
Which material will result in the lightest member if you want to limit the elongation to 0.20 in.? Which material will be cheaper under these conditions?
A car weighing 4000 pounds strikes the stopping barrier depicted below head on at a speed of 70 mph. The stopping force in the barrier is a function of how far the car penetrates into the barrier.
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
If the quantity of ash released from the power plant each minute were to be eventually despersed in 4,000,000 m^3 of air at 25 degrees Celsius and 1 atm, what would be its concentration expressed in ppm
A force P is applied to bent rod ABC, which may be supported in four different ways. In each case, if possible, determine the reactions at the supports.
