Science Behind Sixes – How do they calculate the distance of the six in a cricket match

How do they calculate the distance of the six in a cricket match!

rn

There are several methods to measure the length of six,

rn

Scientific method:

rn

Range of Projectile

rn

This term “Range of Projectile” is associated with physics and to discuss it in the context of cricket six-length determination is quite fine. In this Range of Projectile mechanism, we throw a projectile in the air at an angle without considering the vertical and horizontal components of motion.

rn

1. Based on the angle of hitting

rn

In the context of cricket, we can take cricket ball as a projectile and when a batsman hit a six, it goes at an angle in the air. So, we calculate the length of six on the base of the angle of hitting.

rn

By using projectile formula, we can state:

rn

[R=v² Sin (2θ)/g]

rn

Where: v= velocity at the time of hitting

rn

g= 9.8 m/s² θ= Angle at which ball is hit.

2. With the use of initial velocity and acceleration of the ball

rn

s = ut + 1/2*at²

rn

t = the time the ball stays in the air

rn

u = initial velocity at which the ball left the bat (calculated like bowling speed) a = 9.8 m/s²

rn

s= distance travel by the ball.

rn

HAWKEYE also used to measure the length of six hit by the batsman, Hawkeye is used for many purposes.

rn

What is Hawk-Eye?

rn

Hawk-Eye is a technology used in cricket which gives you a virtual understanding of the angle and distance of where a ball travels once it pitches. One very common use of Hawk-

rn

The eye are the LBW decisions, where the viewers can see the virtual future path of the ball after it’s being pitched and in conclusion get an idea of whether the batsman should have been adjudged LBW or not.

rn

How does it work?

rn

The whole setup involves six high-speed vision processing cameras along with two broadcast cameras. When a deliver is bowled, the position of the ball recorded in each camera is combined to form a “virtual” 3D positioning of the ball after its being delivered. The whole process of the delivery is broken into two parts, delivery to bounce and bounce to impact. Multiple frames of the ball position are measured and through this, you can calculate the direction, speed, swing, and dip of that specific delivery.

That’s how it functions.

rn

To measure the length of the six , they get 3D image from Hawkeye and get the ball trajectory to measure its distance, but they can measure till where the ball hits the stadium and they will not measure the length of the six until where will the ball hits the ground, this is why the Chris Gayle six looks small.

rn

Different Features of Hawk-Eye

rn

Now that we’ve read about Hawk-Eye and its working, there are some other features that this technology brings along with the standard LBW appeals.

rn

Wagon Wheels

rn

So when you see Chris Gayle blast his way to a quickfire 50, it’s also exciting to see the various directions in which he must have sent every bowler packing! The Wagon Wheel gives you an idea of the different areas where the batsman has been targeting to score singles, doubles, boundaries or sixes. Plus, looking at the trajectories of the shots you easily know why Dhoni is one of the most feared batsmen in cricket!

Pitch Maps

rn

This consists of a virtual map of the various areas of the pitch where the bowler has bowled a delivery. It shows you how consistent a bowler is, in terms of line and length. There’s a split-screen format where you can see a bowler bowling to the left and right-handed batsman.

rn

Last but not the least, it also clearly indicates why although being extremely fast, Shoaib Akhtar might just not be the best choice for a bowler in comparison to Glenn McGrath!

RailCam

rn

Another feature of Hawk-Eye, which is aimed at bowlers. RailCam lets you see the difference in speed and bounce between the deliveries bowled either by the same bowler or by different bowlers. While this also talks about a bowler’s line and length, you can see whether he has variations in his repertoire!

Ball Speeds

rn

This is as simple as it gets. Ball Speeds lets you trace the different speeds of a ball after delivery. So, you can see whether a batsman gets knocked out by a fast-paced delivery or fooled by a slower one.

Finally, its broadcaster decision to use which technology to measure the length of six and other things.
