Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have been wracking my brains about how to work out how much force I am calculating when doing some drop testing on armour.

I was wondering if someone woudl be able to walk me through a good way to show this as simply as possible. My physics knowledge is limited but I learn fast so say what you think and I'll ask if I don't get it.

Right my problem is I am dropping various blades onto fabrics from two different heights (1.2 and 0.7m) the drop test machine has minimal friction and just drops straight downwards.

I am using different amounts of cloth to see where it starts to become effective against certain weapons strikes. However the points of blades are obviously microscopic and there is my dilema. I am having difficulty saying how many kilos per m squared force I am giving or how many joules I am releasing within a time frame.

I have some more data if someone is willing to help.

Thanks in advance
