The tangents of a spiral curve have azimuths of 226 degrees and 221 degrees respectively. The minimum length of spiral is 40m. with a minimum super elevation of 0.1m/m. width of roadway. The maximum velocity to pass over the curve is 70kph. Assume with of roadway to be 9m. (Embankment = E = e * width of roadway). Show your solutions and drawing. a.) Determine the degree of simple curve b.) Determine the length of spiral curve. c.) Determine the length of external distance.
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
