Raw rubber from Malaysia is delivered to the factory in ‘bales’

During the time the appearance squash balls manufactu blushful has developed into a highly sophisticated process. Here is investigated how balls are made. To begin with, stinging rubber from Malaysia is delivered to the factory in bales of about 25kg sufficient to make about 1,200 balls. In its natural subject rubber is very stiff and difficult to work, so it is first masticated to a softer consistency.A variety of natural and synthetic substance materials and powders are then mixed with the rubber to give it the required combination of strength, resiliency, and colour as considerably as to enable it to cure (or vulcanise) later in the process. The manufacturers recipe is a no less closely guarded secret than that of Coca Cola, and different combinations of ingredients (as many as 15 are used, including polymers, fillers, vulcanising agents, processing aids, and reinforcing materials) produce fast ( game dot), medium (red dot), slow (white dot), and super slow ( icteric dot) b alls.The current WSF stipulation for the Standard Yellow Dot Championship Squash Ball determines the permitted diameter, load, stiffness, seam strength and tease resilience of the championship ball. No specifications are set for other types of ball, which may be used by players of great of lesser ability or in court conditions which are hotter or colder than those used to determine the yellow dot specification. (http//www. squashplayer. co. uk) Thus, we dont have any exact data (parameters) for red and blue balls.We only can use data available for yellow ball and modify the possible parameters that red and blue balls may have. Out of all specifications of a ball we are interested in its weight and ricochet resilience. Rebound resilience is a measurement of the height a ball bounces off a hard surface. The data given in the table above mean that if unrivalled drops ball from a height of 100 centimetres (1 meter) onto a concrete floor then at 23oC the yellow balls must recoil at 12 centimetres at 45oC between 26 and 33 centimetres.At 23oC the red ball must taunts at 15 centimetres at 45oC between 33 and 36 centimetres. At 23oC the blue ball must rebound at 17 centimetres at 45oC between 36 and 38 centimetres. For our study we will take that if one drops ball from a height of 1 meter, then at 23oC the red ball must rebound at 15 centimeters at 45oC at 34. 5 centimeters. at 23oC the blue ball must rebound at 17 centimeters at 45oC at 37 centimeters.
