1.A horizontal curve was designed for a four-lane highway for adequateSSD. Lane widths are 12ft, and the superelevation is 0.06 and was setassuming maximum fs. If the necessary sight distance required 52ftof lateral clearance from the roadway centerline, what design speed was used for thecurve?

2.If the man at B exerts a force of P = 30 lb on his rope, determine the magnitude of the force F the man at C must exert to prevent the pole from rotating, i.e., so the resultant moment about A of both forces is zero. Please work this out step by step so I can look at the steps and learn how to do this problem and ones similar to them.

3.A 1-m diameter cylindrical mass, M, is connected to a 2-m widerectangular gate. The gate is to open when the water level,h, drops below 2.5 m. Determine the required value forM. Negate friction at the gate hinge and the pulley.
