because there was no way of testing it that way.
we tried several systems using clamps etc but our apparatus was not stable. So the only way that i could hold it and hit it was by clamping the bottom half in the technology departments workbench and striking the top off.
So I still have my...
thanks for your responce but i still have my initial problem.
after finding the pressure required to break the joint in the board by holding the bottom and striking the top i have no way to relate this to how much pressure is required to break the joint if i strike it in the middle
any ideas?
hey cheers for your responce but i was led to believe that to work out 'how hard the board needs to be hit' i would have to find the sheer breaking force. this would be determinned by hitting it and not by adding weights until it breaks.
the boards are not actually wood as i stated but a very...
In my A level physics class i have decided to find the amount of force required to break a karate striking board and relate it to how much force is required to break a human rib and a jaw etc
The striking board is basically a board that has been cut in half so there is a snapping line across...
1. Hello, I need to devise myself a practical coursework and i have chosen to find out how several variables effect the power of a swinging mass striking an object.
Variables:
I will use a motor to swing an arm of 30cm with a 1kg mass attached to the end with a time period of 1 second. The...
