2, diameter not less than 42.67 mm 3, have the symmetry of the sphere, that is, to round Rights can not be grotesque to 4, there is the sum of the ball's initial velocity and distance standards are all qualified, can not exceed the relevant provisions of

golf is a hard texture , flexible, solid white ball like a tennis-sized, made of elastic rubber, the maximum weight of 1.62 oz. According to U.S. regulations, the ball's diameter is 1.68 inches, 1.62 inches in accordance with the provisions of the United Kingdom.

Club is divided into head, rod stem, bar the three parts. Striking the head, grip the pole position for the connecting rods of head and rod is the rod to the stem. Any contact with the ball head, said inclined face. Perpendicular with the ground face of the tilt angle is still referred to as head ascribed angle. Angle of each club are inconsistent with the impulse, the greater the angle, this means a greater number of clubs, hit the ball higher. In general, the longer the club, head shot up the smaller the angle, hit the ball the more distant (special push aside push the ball rolled into the hole) rods, no head shot up corner, not in this case). Club length and club number inversely proportional to the angle with the head ascribed inversely proportional to the distance with the ball.

There are two clubs, divided into the woods and irons. Wood into five types according to their length. Irons is divided into nine types according to their length. Irons have used three different shots: pitching wedge, head ascribed angle greater within the 100 yards for beating lofty goals; sand bar, easy to hit the ball in the sand; call the bar, post on the green hit with. Various number of clubs hit the ball from Table 13: Table 13

distance (code units) 100 110 120,130,140,150,160 170,180,190,200,210 220 Wood 5 4 3 2 1

Irons pitching wedge, 7, 8, 9, 5, 6, 2, 3, 4, 1

usually hit the ball long distance use wood, in order to find the ball accurately, use the iron. No. 1 wood club the longest, ascribed the smallest angle, hit the ball effectively, known as open clubs, often in the four holes and five holes on the kick-off site use. 2, 5-wood fairway in good use. 1 to 3 iron as a long iron rod length and weight, high jump shot far, but difficult to master. 4 to 6-iron that the iron, hit a high, still capable of rolling the ball falls to the ground some distance. 7 to 9-iron known as short irons, often at close range and hit the ball hard and deep position on the use of grass. 9-iron shot up the largest angle, hit the ball high, resulting in a larger inverted spin, less rolling after landing. Pitching wedge is the shortest one iron. Mainly by using a variety of golf clubs of varying lengths, control ball distance and height. Therefore, each player does not have to have more than 14 various models of a set of clubs normally include 3-4 wood, 7 iron, pitching wedge, sand bar, and putting aside. Xu Yong with a complete set of woods and irons which, by the player himself to decide.
