To measure and obtain the force applied by shot put athletes, the Robot Sensor Lab of Institute of Intelligent Machines, Chinese Academy of Sciences used analytical and experimental approaches to develop a three-axis force sensor and design a digital shot for coaching of shot put athletes [4].
The digital shot is made up of steel materials, and its size and weight in line with the specification standard of female shot put formulated by International Association of Athletics Federation, so as to provide shot put athletes and researchers a practical environment to conduct experiments, and the information acquired will be more accurately.

Compared with the traditional saving way by paper, it can not only save the precious data of soil census effectively by computer technology to supply detailed data for the various agricultural planning and forecasting, but also can make complex space analysis to all kinds of soil data to supply reliable materials for the various agricultural planning and deciding, which is good for the using and sharing of the soil data and promote the development of "digital agriculture".

Those factors include materials, shape of housing, internal structure, type of cable material, and type of driver unit.
These materials determine the quality and timbre of sound they produce.

Introduction Machinability of materials is characterised by few indicators such as: tool wear, quality of machined surface, cutting temperature, cutting forces, etc.
Forces in surface grinding, measured with dynamometer Kistler, are increasing with increase of the material removal rate.
It can be seen that genetic algorithms generated more suitable coefficients and thus produced smaller error for most of the forces and materials except for tangential force Fr for steel EN 34Cr4.
