A curve of 80m radius is banked at 7.5 degrees to the horizontal. A car of mass 1.5 tonnes has to negotiate this bend. The coefficient of friction between the tyres and the road is 0.8. Calculate: 1. The side pressure on the tyres when the car is stationary in the bend. 2.The speed at which this car would experience no side pressure on tis tyres when rounding the bend. 3. The speed at which this car would be on the point of skidding in this bend.
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.
