I'm wondering if you could help me with a problem I am having. I am currently mid process of designing a device used to measure tension in a tennis net, and I am stuck at trying to calculate the deflection in the net cord on ball impact.

I have calculated that the ball will impact the net with a force of around 6492.14676 N by using the extremes for a mens serve, ball dimensions and the weight. The recommended tension in the net cord is 500lbs, i have tried to model the system as a beam and work out deflection, but have had no joy, can you please help me!

Many Thanks
