Design the continuous slab showin using the ACI moment coeficients assuming the service live load of 200 psf is to be supported in addition to the weight of the slabs. The slabs are to be built integrally with the end supports, which are spandrel beams. fy = 60,000 psi, fc' = 4000psi normal-weight concrete. Clear spans are 15 feet, 18 feet and 15 feet. with the longitudal span of 38 feet.
design a horizontal curve with a 40-degree central angle ( delta = 40) for a two-lane road with 11-ft lanes. The design speed is 70 mi/h and superelevation is limited to 0.06 ft/ft. Give the radius, degree of curvature, and length of curve that yo..
A cylindrical metal specimen 12.0 mm in diameter and 120 mm long is to be subjected to a tensile stress of 40 MPa . at this stress level the resulting deformation is totally elastic.
A proton feels a force of 2.0 micro-Newtons in the negative x-direction when it is moving in the positive y direction with a speed of 2.0 x 107 meters per second.
What superelevation rate would you recommend for a roadway with a design speed of 100 km/hr and a radius of curvature of 500 m? Assume f = 0.11.
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
Force P is directed from point A(5,10,3) towards point B(1,-2,5) and has a magnitude of 15N. Vector Q=6i+2j-5k. When finding the projection of P onto Q what do you do with the 15N
A particularly long traffic light at an intersection is green 20% of the time. A car approaches this intersection once each day. Let X represent the number of days the car encounters a green light.
