2.A section of a road has a superelevation of .6% and a curve of 600ft radius. What speed limit will you recommend at this section of the highway?
3.Find the limiting length of an offset so that the displacement of a point on paper is may not exceed 0.025 centimetres.The offset was laid 3 degree out from it's true direction and the scale was 10m to 1cm.
A tank is filled with oil (specific gravity 0.8) and water to a depth of 10 meter and 6 meter respectively. Find the resultant force from all fluids acting on the gate of 1.8 meter by 9 meter.
In a study it was found that 39% of the bacteria died within 9 hoursand 67% died within 20 hours. If the rate of andwer proportional to the number remaining, how long would it take to obtain a 99.9% reduction in the bacteria
A body weighing 120 lb with a flat surface area of 2 ft^2 slides down a lubricated inclined plane making a 30 degree with the horizontal. For a viscosity of 0.002 lb*s/ft^2 and body speed of 3 ft/s, determine the lubricant film thickness.
