Find the degree of curve of a central simple curve if it has spiral curve 100m. long on two sides, on which a car traveling at 75 kph will not skid. Use arc basis.
Solution:
The center height of the road at station 5 + 320 is 4.25m. cut. At station 5 + 420 it is 1.80m. fill. The ground slopes uniformly at -5% from station 5 + 320. How far from station 5 + 320 toward station 5 + 420 will the excavation extend.
Solution:
Determine the area of the spherical triangle ABC if A = 140°, B = 75°, C = 86° and r = 40m.
Solution:

Solution:
The upper and lower bases of a frustum of a regular rectangular pyramid are 3m x 4m and 6m x 8m respectively. If the volume is 140cu.m., what is the distance between the bases in meters?
Solution:
A cylindrical with an altitude of 15cm. has a base in the form of a regular octagon inscribed in a square 10cm x 10cm. Find the volume of the cylinder in cubic cm.
Solution:
A closed conical vessel has its horizontal base at the bottom and its axis vertical. The water in its stands 0.5m. deep. The base radius is 1 m. and the altitude is 2.5m. The vessels position was changed such that the horizontal base was uppermost. Find the depth of the water from the bottom.
Solution:
