So this is my physics coursework and i need to know what actually happens during the knocking in procedure?
I also dont know any tests i can do to test any improvement. I.e using Youngs Modulus/Stress/Strain during contact with the ball etc.
Im also not really sure on the correct word for compressing willow, is the material tough/hard/stiff?
My explanation is that the particles compress together which makes the material stronger (need correct word if poss) and improves the co-efficient of restitution, and makes it less likely to break. Any ideas?
Thanks
