4.2 A 200 m long sag curve is used under a grade separation structure. The curve joins an entry grade of - 3% and exit grade of + 5%. If the required vertical clearance is 5.5 m, determine the available sight distance over the curve. Assume driver eye height and dangerous object height of 1.8 m and 0.15, respectively. If the information available is not complete, please assume and specify a reasonable value and continue with the assignments.

A sag vertical curve is to join a grade of g1=−3.50% to a grade of g2=−1.25%. What is the minimum length of the curve for acceptable passing sight distance at night, with headlight illumination? Express your answer in feet to five significant figures. there is no more info. this is all that was given to us.

A vertical sag curve connects two tangents with grades -3% and +2% with the design speed of 100 km/h. (a) Calculate the available sight distance and the length of the vertical curve using the minimum flatness of curve that will satisfy the headlight criterion during dark conditions. Assume the height of the headlight above the pavement is 0.6 m and the angle of the light beam upward from the axis of beam is 1. (a) Assuming that the length of...

You have a symmetrical sag vertical curve of Length = 6 stations. The entering tangent from the left has a gradient of –6% and the exiting tangent has a gradient of +4%. The VPC Station has an elevation of 250.00 feet (which will be your C-Value) and its station distance is measured to be at 40+00 stations. You will now do the following: Find the elevation and station of the VPI. Find the elevation and station of the VPT Find...

A 280m long equal tangent sag vertical curve has its PVC at chainage 2950.00m and elevation 76. 520m.The initial grade is -3.89% and the final grade is 1.02%. (20) a. Make a neat free hand drawing to illustrate a long section of this curve. b. Calculate the chainage and elevation of PVI c. Calculate the chainage and elevation of PVT d. Calculate the chainage and elevation of the lowest point on the curve.

Answer A- H please a) Draw a Supply Curve and the Demand Curve for the Sugar Label the supply S1 and the demand D1. Label on the vertical axis P for the equilibrium price and label the horizontal axis Q for the equilibrium quantity. We currently have the sugar market in equilibrium at a price of $3 per pound and 100,000 pounds. Now assume that the state government just announced a new price floor program for the sale of sugar....
