The super elevation of the railroad tract is the number of inches that the outside rail is raise to prevent side trust on the wheel flanges of cars rounding the curve at rate speed. Determine the super elevation e for a track a gauge of 4 ft - 8 ½ in of 2000 ft radius and a rate speed of 60mph.
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
