In a volleyball game, the tension of a net can have a great influence on the outcome of the game. For example, when the ball touches the net, it will affect its direction which can result in an additional score and the power of the rebound can also affect the players. However, there is no specific regulation on the tension of the net. We find it necessary to set a guideline of the net tension in order to provide safety as well as the durability of the equipment. Here in this report, we took measurements of the net rope tension to inspect the force given to the net and the standing poles. The report gives data of relevant measurements of the tension considering the strength of the poles within safety bounds and it also introduces machinery which can measure the net tension.
