How are tennis rackets tested?
Tests are performed to measure tensile strength, elongation at break, knot strength and elongation percentage at given loads. Elongation is measured at 45kg force to replicate the ball hitting the strings. Knot strength is measured because if this is too low, the string will break.
How much does it cost to demo a racket?
Demoing a new racquet with Tennis Express is so easy. You may demo up to three racquets online for a small fee of $24.95 which includes shipping the demos to you and a pre-paid UPS return label to ship the demos back to Tennis Express (Note: All demo racquets in your order will be shipped together.
What is a demo tennis racket?
Most major tennis retailers and local racquet shops (sadly dwindling) offer a demo program where you can select several racquets, get them shipped to your home (or collect in-store), use them for a week or two and then send them back. No strings attached 🙂
How long does it take to get used to a racquet?
I used basically the same racquet for 7 years and I could hit fine after two weeks with the new one, confident playing matches in 6 weeks, but I think to be totally comfortable with the new one took 6 months to a year+.
Can you restring demo racquets?
TW Staff said: , but we can’t allow customers to re-string demos. Too many problems can occur (as we have experienced in the past). We hope that you can get a good enough gist of the racquet to be able to make a decision whether you like it or not by the string and tension we provide.
Can I restring a demo racquet?
If you get a demo from a shop it’s usually with a used string setup that might not be idea for that racquet. This is why it makes sense to restring the racquet if possible. Pairing a racquet with the right string might sometimes be an issue so go with your favorite string that you already know well.
Is it bad to leave tennis racquet in the car?
It is advisable not to leave your racket in the car, regardless of the prevailing temperatures outside. The car tends to heat up to extreme levels, which is harmful to your strings and racket frame, depending on its material. If the same thing happens to your racket, the strings get loose and lose their tension.
How much does a tennis racquet weigh?
Sometime you’ll get weird numbers that arent correct depending on stringbed and material, (EX: string racquet at 52 lbs. verify at 52 lbs with meter. String crosses at 52 lbs, meter says mains are now 70 lbs, tuning app puts strings at 52lbs.
How to test the Mains of a racquet?
There’s a section calibrated to test an unstrung racquet in which you can test the mains only before doing the crosses. If they vary you can push down on the tighter strings so the looser ones will compensate to make for even string tension across the mains.
Why material testing is important for tennis rackets?
Material testing of tennis, badminton and squash rackets helps racket manufacturers assess quality during production, with measurements such as impact strength, durability, fatigue, torsion strength and flex being important tests for quality assurance. In addition, tensile testing plays an important role in string production.
How to choose the right tennis rackets?
Measure the impact strength, durability, fatigue, torsion strength, flex and standard bench, weight and balance of your tennis rackets. Materials testing is a well-established technique used to determine the physical and mechanical properties of raw materials and components from a human hair to steel, composite materials and ceramics.
