Mention the three styles of shot-put.
Answers
The shot put (pronounced /ˈʃɒt pʊt/) is a track and field event involving "putting" (pushing rather than throwing) a heavy spherical object—the shot—as far as possible. The shot put competition for men has been a part of the modern Olympics since their revival in 1896, and women's competition began in 1948.
The shot is made of different kinds of materials depending on its intended use. Materials used include sand, iron, cast iron, solid steel, stainless steel, brass, and synthetic materials like polyvinyl. Some metals are more dense than others making the size of the shot vary. For example, different materials are used to make indoor and outdoor shot - because damage to surroundings must be taken into account - so the latter are smaller. There are various size and weight standards for the implement that depend on the age and gender of the competitors as well as the national customs of the governing body.
