A simple curve having a degree of curve equal to 40030’ has a central angle of 50050’. It is required to replace the simple curve with another circular curve y connecting a transition curve (spiral) at each ends by maintaining the radius of the old curve and the center of the new central curve is moved away by 5 m. from the intersection point. Determine the central angle of the circular curve Compute the tangent distance Ts of the spiral curve What is the maximum velocity that a car could pass thru curve without skidding?

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
