The normalized peak contact pressure and the contact length along the male sides are numerically evaluated. 1 Introduction Polygonal contacts are encountered in keyless polygonal joints, employed as an alternative mechanical coupling to keyed joints in the transmission of torque between two shafts, [1, 2].
In [5], on the basis of engineering judgment, it is assumed that a) the pressure profile is triangular; b) one half of the length of each side of the polygonal profile is in contact, whereas separation takes place in the remaining side portion.
A linear elastic material with elastic constants typical of steel was adopted.

The Design Of A Basketball Goal Automatic Detector Jianjun Zhang1, a, Jinbao Yang1, b, Zhimin Tang2, c, Hao Lan1, d and Haijun Lin1,e 1College of Engineering and Design, Hunan Normal University, Changsha 410081, China 2College of Electrical and Information Engineering, Hunan University, Changsha 410082, China ajianjun998@163.com, byjbmail2004@126.com, c1003306213@qq.com, dlh1075616@tom.com, elinhaijun801028@126.com Keywords: Ultrasonic, Infrared Sensor, Single Chip Microcomputer, Basketball shooting, Physical Testing.
Because the entrance examinations of physical education specialty used artificial means to carry out, particularly in basketball, volleyball and other professional subjects tested, the professional entrance examination requires a lot of manpower and material resources, and the highly focused attention of the invigilators, resulting in slow testing, high error rates, more human factor, and injustice and other problems arise [1].
The design of system Functions Design By actual inspecting for a long time, attentively reading " The Winner of the Physical Education and Sports Competitions Testing Standards (2012 Edition) ", [4] and with the subject organizers' opinion, we believed that the basketball goal automatic detector should have the following key function indicators: 1).
