Hi Jrmichler, Thank you for your reply, I will look at the book you provided, I'm planning on doing experiment with various wood species to find if there is a correlation between the density of the timber, young modulus and the force needed to drive the nail into the wood.

lets say a hammer of 0.5kg strikes a nail at 10m/s. The nail penetrates into the wood by 1cm. The reason why the nail stops is because friction has eventually overcome the nails momentum. The retardation of the nail can be worked out, but Can you calculate the force that stops the nail if you...
