# Sports Equipment -To carry out tests on different types of grip.

Extracts from this document...

Introduction

INTRODUCTION During this last month or more we have been working on a project called "sports equipment". We carried out 5 tests during this project, which I will explain and give an explanation on how and what we did. The 5 tests were: 1. Grip (Friction) 2. Tensile strength 3. Resistance to wear 4. Stiffness 5. Density We tested all these on a trainer (shoe). We tested them on a trainer because we had to test it on sports equipment so we thought that there isn't better sports equipment better then a trainer (shoe) to chose, because the trainer has all these things we wanted to test. It has grip (friction) on the soul of the trainer (shoe). For the tensile strength it had a lace on the trainer (shoe), which we could check. For resistance to wear we wanted to check how long the trainer (shoe) would take to wear out and by looking at that we would have found out which trainer (shoe) is better. We wanted to check for stiffness to find out weather the trainer (shoe) is comfortable or not. We wanted to check for density to check how heavy the trainer (shoe) is. AIM: To carry out similar tests to test different types of grip. INTRODUCTION: An athlete will regularly require to construct a good grip, for instance on the running track (so they do not lose they balance over the surface) or the handle of a tennis racket (so when the ball is hit the racket does not twist in their hand). In a sports circumstance, grip refers to friction between surfaces. To make sure during these last couple of lessons we carried out an experiment to observe how friction works on different surfaces. We tested the friction using four different types of trolleys will four different surfaces on the wheel. To do this we had to put the on running tracks. ...read more.

Then put a number of weights on it till it bends 4. When it bends write down the number of weights it took you to get the rod bend in kg's or g's 5. Then do the same for the rest. I used the same method as the method above. I got the following results. Steel rod = 1.5kg Brass rod = 1kg Gold rod = 5.7kg Copper rod = 900g I did these tests each three times to make sure that they were accurate. What I think was that if there is a lot of the rod sticking out it holds less weights but if there is not a lot of the rod sticking out it holds a lot more weight. According to my test I did all the tests the same I made sure they were accurate. And that they were all done the same. Then I did the same to check the lace of a trainer (Shoe) I used the same method as I used to do the rods. But the lace was to hard to brake down so I took a strand out of it and these were the results of a single strand of a lace. My results were: NIKE - 678 N/mm2 that was the strength so to make sure I asked my friend for his results. His trainer (Shoe) is a FILA trainer (Shoe). FILA - 117.3 N/mm2 His results stunned me because I was thinking that it will be around about the same but I had a big difference. So then I asked my other friend for his results he has got a NIKE Total 90 Astroturf trainer (Shoe). Total 90 - 67.3 N/mm2 I wasn't so surprised looking at his results then looking at mine because they were pretty much the same so that was alright but I still think that the FILA trainer (Shoe) ...read more.

Conclusion

MASS (g) DENSITY By looking at these results it tells me that the more the mass the higher the density. So then I decided that I do the same for my trainers (Shoes) points. NIKE - HEAL - mass 42.1 Volume - 20.5 Density - 2.0536585 SOLE - mass 63.7 Volume - 16.3 Density - 3.907975 INNER SOLE - Mass - 21.6 Volume - 12.2 Density - 1.7749 TOE PROTECTION - Mass - 17.4 Volume - 32.5 Density - 0.5353846 I was pretty pleased with my result on the mass, volume and density but still to make sure I asked my friends for his results. FILA HEAL - mass - 29.1 Volume - 14.5 Density - 2.006 SOLE - mass 63.7 Volume - 16.3 Density - 3.907975 INNER SOLE - Mass - 21.6 Volume - 12.2 Density - 1.7749 TOE PROTECTION - Mass - 17.4 Volume - 32.5 Density - 0.5353846 These where my friends results that the I had asked him for I think that these results where not so good. So then I asked my other friend for his results and there pretty much the same. NIKE Total 90 HEAL - Mass - 31.4 Volume - 23.1 Density - 1.36 SOLE - Mass - 23. 4 Volume - 31.1 Density - 0.75 INNER SOLE - Mass - 16.5 Volume - 12.3 Density - 1.341 TOE PROTECTION - Mass - 24.7 Volume - 11.4 Density - 2.1666666666666666666667 These results where not so pleasing these results where not well so I am pretty upset with them EVALUATION FOR ALL I think that if our school had more money the experiments would be better than they are they are not so bad but they would be better with better equipment. Overall I think that all the experiments went good but I think with better equipment they would be better. The work that I did was went very good and hopefully I am looking forward for more experiments in my future career.

This is known as the collision theory. However, because aluminium is a shiny metal, it reflects more heat than it absorbs heat which may have caused the reduction of heat retention. The results also indicate that my prognostication at the start was miscalculated or was effected by some incorrect procedures during the experiment.
