How to Calculate a CrossSectional Area | Sciencing

Nov 13, 2018· Any plane can be used to cut through the surface, but when that plane is perpendicular to an axis of symmetry, its projection is called a crosssectional area. For a simple threedimensional shape, such as a cylinder, the crosssectional projection is a circle, and the area is easy to calculate.

Crosssectional area of a baseball? | Yahoo Answers

Oct 09, 2010· I've got a physics problem I'm working with and can't figure out how to find the crosssectional area of a baseball. So, a pitcher throws a pitch at 93 mph, or m/s, and the batter hits it at a 40 degree angle. The mass of the ball is .145 kg, and the diameter is I need to find the x and y components, which I'm assuming is just (40) for the x and (40) for the y, and ...

Physics Chapter 1 Measurement. Then, with a crosssectional area of d 2 and a length L, the string occupies a total volume of V = d²L. This is approximately equal to the volume of the ball, given by 4/3 (pi)R³, which is about 4R³ because p is about 3. Thus, we have the following: d²L = 4R³. Solve for L, and you get 2 x 10⁶ m, or about 10³ km.

The physics of baseball.

The bat and the ball The character of baseball has evolved as a result of delicate balances—between hitter and pitcher, between bat and ball. Drop a baseball onto concrete from 10 feet and the ball will bounce up only about 3 feet; the coefficient of restitution is then about 10 =

Drag on a Soccer Ball Glenn Research Center

May 05, 2015· On this page we will discuss some of the details of the drag on a soccer ball. The details of how a moving soccer ball creates drag are fairly complex. If we move with an object through the air, the object appears to stand still and the air moves past the object at the speed of the object. ... A is the crosssectional area, and cd is the drag ...

May 05, 2015· where D is the drag, A is the crosssectional area, and cd is the drag coefficient a number that represents all of the complex factors affecting drag. Drag coefficients for a specific object are determined experimentally using a model in a wind tunnel. For flow past a ball, determining the drag coefficient gets a little more confusing.

Average your crosssectional areas (A): Using the average area and corrected velocity, you can now compute discharge, Q. Q = Cross section area (A) * mean velocity (ʋ) Essentially the cross section technique estimates each of the terms on the right hand side of the equation(s) and multiplies them together. The cross section area of the channel is
