The only thing which doesn’t require the knowledge of study in the world is sports but it is no longer going to be the same as IIT Kanpur institution has found a link in their Physics law to cricket. They introduced few -physics laws which can yield the reverse swing for fast bowlers. Reverse swing has always been the lethal option for the bowlers and IIT Kanpur are trying to making it a common thing in Indian cricket.
As per DNA India, Professor Sanjay Mittal and his two students Ravi Shakya and Rahul Deshpande of the Institute’s Aerospace department were conducting a series of research to unravel the mystery behind different swings by pacers on the cricket pitch. After research on the run-up, bowling action, technique, delivery etc of different well-known swing pacers in the world, the research team connected the swing on the pitch in their laboratory with a formula of physics.
Prof Mittal claimed that it was easier for any pacer (medium or fast) to deliver a reverse swing by applying a simple formula of physics and changing his action at the final delivery of the ball. He claimed that if a pacer delivers the ball by turning the seam 20 degrees downward with a pace of 30 to 119 km/hr speed, he gets the maximum swing, depending upon the weather conditions.
The Professor and his team claimed that if the ball is bowled at the speed between 119 and 125 km/our, the bowler with this formula can get reverse swing in the first trajectory and natural swing in the other, which is often called late swing in cricket. Imran Khan was famous for this kind of reverse swing, which used to be called his deadly in-dippers.
They also studied the connection between surface / roughness of the ball and swing and found that rough surface of the ball/pitch help medium pacers with speed of 20 and 70 km to produce natural swing while pacers throwing the ball at the speed 79 to 140 km/hour and above gets reverse swing if they knew the physics behind producing swings.
Ball tampering cases are due to this reason when a pacer tries to make the ball surface rough with his nails or using some pointed objects to bring down the thickness of the ball by one mm. This condition of the ball helps pacers generate more swings than the usual ball.
