## Driving the racing line: turnin, apex, exit

The apex is the point at which you are closest to the inside of the corner, also referred to as the clipping point. Once you have hit the apex you should be able to reduce the steering lock, start increasing the throttle and focus on the exit.

## How to get surface area of a cone using integral calculus ...

Apr 09, 2018· Adding an infinite number of these circumferences together results in the lateral surface area of the cone. We accomplish this by using the function of a circle, and using an integral to calculate its arc length, and evaluating it between 0 and h. This will give us the circumference of half of the circle.

## How to Calculate Pyramid Angles | Sciencing

Apr 24, 2017· Used in many structures, temples and tombs around the world, the square pyramid has contributed to countless human constructions. Pyramids are polyhedrons (solid, three dimensional objects composed of flat faces and straight edges), and are formed when a base and its point, known as an apex, are connected by triangles.

## Spot Drill Tip Calculator >

If spot drills came to a true point, calculating their drill depth would be easy, due to the fact that the depth would equal the radius of the desired chamfer or the hole radius plus the chamfer radius, since a 45° angle is employed in the depth calculation as shown in .
