You are asked to design a horizontal curve for a two-lane road. The road has 12-ft. lanes. Due to expansive excavation, it is determined that a maximum of 34 ft. can be cleared from the road's centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximum super elevation of .08 ft/ft. What is the highest possible design speed for this curve?
The two upper lengths of the welded Y-shaped assembly of uniform slender rods have a mass per unit length of 0.3 kg/m, while the lower length has a mass of 0.7 kg/m. Locate the mass center of the assembly. lenghts of all rods aew 30mm
A flow of 90 cfs is carried in a rectangular channel 10ft wide at a depth of 1.6 ft. If the channel is made of smooth concrete (n=0.016), find the slope necessary to sustain a uniform flow at this depth.
A beam with a 20 ft simple span has cross- section dimentions b= 12" d=12 in and h=25in . it carries a uniform service load of 2450 lb/ft in addition to its own weight. material strengths are f'c=4000psi and fy=60000psi .assume a weight od 150 pcf fo..
A grain-size analysis for a uniform sand in a loose state indicated that the soil particle diameter corresponding to 10% passing on the grain-size distribution curve is 0.18 mm. Estimate the coefficient of permeability.
