The Swing of a Cricket Ball
SCIENCE BEHIND REVERSE SWING C.P.VINOD CSIR-National Chemical Laboratory Pune BACKGROUND INFORMATION • Swing bowling is a skill in cricket that bowlers use to get a batsmen out. • It involves bowling a ball in such a way that it curves or ‘swings’ in the air. • The process that causes this ball to swing can be explained through aerodynamics. Dynamics is the study of the cause of the motion and changes in motion Aerodynamics is a branch of Dynamics which studies the motion of air particularly when it interacts with a moving object There are basically four factors that govern swing of the cricket ball: Seam Asymmetry in ball due to uneven tear Speed Bowling Action Seam of cricket ball Asymmetry in ball due to uneven tear Cricket ball is made from a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam Dimensions- Weight: 155.9 and 163.0 g 224 and 229 mm in circumference Speed Fast bowler between 130 to 160 KPH THE BOUNDARY LAYER • When a sphere travels through air, the air will be forced to negotiate a path around the ball • The Boundary Layer is defined as the small layer of air that is in contact with the surface of a projectile as it moves through the air • Initially the air that hits the front of the ball will stick to the ball and accelerate in order to obtain the balls velocity. • In doing so it applies pressure (Force) in the opposite direction to the balls velocity by NIII Law, this is known as a Drag Force. -

Start a Premium Handcrafted English Willow Cricket Bat Manufacturing
Y-1743 www.entrepreneurindia.co www.niir.org INTRODUCTION A cricket bat is a modified piece of equipment that batsmen use to strike the ball in the sport of cricket. It usually consists of a cane handle connected to a flat-fronted willow-wood blade. A batter who is making their ground will do it to prevent being run out if they keep the bat and hit the ground with it. The bat must be no longer than 38 inches (965 mm) in length and no wider than 4.25 inches in width (108 mm). The first time it was seen was in 1624. Since 1979, a law has required bats to be made entirely of wood. www.entrepreneurindia.co www.niir.org MANUFACTURING OF ENGLISH WILLOW CRICKET BATS Willow wood and cane are used to make the cricket bat. The handle of the bat is made of cane, and the blade of the bat is made of willow. Willow wood has properties that allow it to absorb shock. When the ball is struck hard and quick, it is difficult to bat. The shock is absorbed by the willow tree. The production of cricket bats goes through many stages in order to produce the highest quality bats. Various steps in the production process are included, from planting willow trees to playing cricket on the field. Kashmir willow and English willow are the two major bat-making woods in India. www.entrepreneurindia.co www.niir.org Step 1:- Plating willow trees and cane: Wood is the most popular raw material used in the production of cricket bats. -

Design of Neck Protection Guards for Cricket Helmets
Design of Neck Protection Guards for Cricket Helmets T. Y. Pang a and P. Dabnichki School of Engineering, RMIT University, Bundoora Campus East, Bundoora VIC 3083, Australia Keywords: Cricket, Helmet, Neck, Guard, Design. Abstract: Cricket helmet safeguards have come under scrutiny due to the lack of protection at the basal skull and neck region, which resulted in the fatal injury of one Australian cricketer in 2014. Current cricket helmet design has a number of shortcomings, the major one being the lack of a neck guard. This paper introduces a novel neck protection guard that provides protection to a cricket helmet wearer’s head and neck, without restricting head movements and obstructing the airflow, but achieving a minimal weight. Adopting an engineering design approach, the concept was generated using computer aided design software. The design was performed through several iterative processes to achieve an optimal solution. A prototype was then created using rapid prototyping technology and tested experimentally to meet the objectives and design constraints. The experimental results showed that the novel neck protection guard reduced by more than 50% the head acceleration values in the drop test in accordance to Australian Standard AS/NZS 4499.1-3:1997 protective headgear for cricket. Further experimental and computer simulation analysis are recommended to select suitable materials for the neck guards with satisfactory levels of protection and impact-attenuation capabilities for users. 1 INTRODUCTION head and facial injuries (Ranson et al. 2013).

Bowling Performance Assessed with a Smart Cricket Ball: a Novel Way of Profiling Bowlers †
Proceedings Bowling Performance Assessed with a Smart Cricket Ball: A Novel Way of Profiling Bowlers † Franz Konstantin Fuss 1,*, Batdelger Doljin 1 and René E. D. Ferdinands 2 1 Smart Products Engineering Program, Centre for Design Innovation, Swinburne University of Technology, Melbourne 3122, Australia; [email protected] 2 Department of Exercise and Sports Science, Faculty of Health Sciences, University of Sydney, Sydney 2141, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-3-9214-6882 † Presented at the 13th conference of the International Sports Engineering Association, Online, 22–26 June 2020. Published: 15 June 2020 Abstract: Profiling of spin bowlers is currently based on the assessment of translational velocity and spin rate (angular velocity). If two spin bowlers impart the same spin rate on the ball, but bowler A generates more spin rate than bowler B, then bowler A has a higher chance to be drafted, although bowler B has the potential to achieve the same spin rate, if the losses are minimized (e.g., by optimizing the bowler’s kinematics through training). We used a smart cricket ball for determining the spin rate and torque imparted on the ball at a high sampling frequency. The ratio of peak torque to maximum spin rate times 100 was used for determining the ‘spin bowling potential’. A ratio of greater than 1 has more potential to improve the spin rate. The spin bowling potential ranged from 0.77 to 1.42. Comparatively, the bowling potential in fast bowlers ranged from 1.46 to 1.95.

Dear Youth Batting Helmet Manufacturer, As the Popularity Of
Dear Youth Batting Helmet Manufacturer, As the popularity of face protectors (c-flap, etc.) increases throughout baseball and softball, Little League® International has begun to receive inquiries from our families, players, and volunteers as to whether or not they’re permitted in Little League play. The safety of all our participants is our utmost concern, and, like the vast majority of youth organizations, Little League requires our batters to wear helmets that meet National Operating Committee on Standards for Athletic Equipment (NOCSAE) specifications and bear the NOCSAE stamp. As face protectors, like the “c-flap,” are additions to a helmet, which require for holes to be drilled in most helmets to affix protector, Little League International contacted NOCSAE for guidance. On May 8, 2018, NOCSAE issued a release, which includes the following information: Products designed to be added to previously certified helmets for baseball, softball, football, lacrosse and other sports are being marketed and sold to consumers. Whether intended to be general improvements or expansions of the helmet’s protective coverage or ability, or to collect impact data, the addition of such products to a helmet previously certified as meeting the appropriate NOCSAE standard will make the certification voidable by the helmet manufacturer. Such additions to the helmet create a new and untested model, as defined in the NOCSAE standards. For many years NOCSAE standards have defined a helmet model as a helmet “intended to be identical in every way, except for size.” Any changes, additions or alterations of the model, except for size or color or graphics, even if made by the original manufacturer, requires that a new model name be created, and a separate certification testing data for that new model. -
Everything You Need to Know About GM Cricket Bats Willow Grading
Everything You Need to Know About GM Cricket Bats Willow Grading Experienced cricketers understand that there’s more to a cricket bat’s anatomy than its length, shape, and weight. You also have to learn about other parameters, such as profile, edge thickness, and willow grading. All these factors impact stroke play and your overall batting performance. If you’re planning to buy a GM cricket bat, you’re at the right place, as we’ll share everything you need to know about Gunn & Moore’s English willow grading. What Is a Cricket Bat Willow? Traditionally, all cricket bats are made from willow wood which comes from around 400 species of deciduous trees and shrubs. These fast-growing, straight trees are tough but incredibly lightweight, which makes them ideal for cricket bats. The most common types include English and Kashmir willow, which differ in terms of quality and, therefore, price. English Willow vs. Kashmir Willow Several factors separate English Willow from Kashmir Willow. However, English willow is much superior to the latter and is the go-to choice for Gunn and Moore. Let’s check out the main differences: Color English Willow bats are relatively lighter than their Kashmir counterparts, which are more reddish. Weight Kashmir willow is slightly heavier, which is ideal for players who prefer heavier bats. However, those looking for lighter options will fare better with English willow bats since their lightweight allows for thicker edges and spines. Durability English willow is grown in wetter conditions, making it more durable compared to the drier, crack-prone Kashmir willow. -
