A particular crest vertical curve has long been criticized as being unsafe. Its length is 400 ft. The prevailing speed on the crest vertical curve is 50 mph. In its present condition, its tangent grades are +2% and -3%. Does this curve meet minimum SSD according to the AASHTO. If it is possible to enforce a speed limit of 45 mph on the curve, will the vertical curve meet minimum SSD standards?
Assuming that silt is equivalent to a liquid having a density of 1760 kg/m3, determine the overturning moment of silt and water about point A.
An increment of vertical stress of150kpa compress the sample to a void ratio of1.43. What is the over consolidation ratio of the soil at the unloaded condition.
a spherical balloon inflated sos that the volume is increasing at the rate of cubic meter/min. At what rate is the diameter increasing when the diameter is 12 m?
If a logit model is estimated with coefficients of -0.543 for distance and 0.0165 for commercial space (in 1000 of ft^2), how many shopping trips will be made to each of the four shopping centers?
a cantilevered bean has a lenght of L, a cross section area of A, and a flecural rigidity of EI. The free end is free to rotate and displace due to bending. derive the stiffnes of the cantilevered bean. Assume small deformations.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
