There is a very interesting article on “Bridge Swinging and the Maximum Tension in a Pendulum String” by Edward P. Wyrembeck (Howards Grove HS, WI) posted on our Vernier Idea Board. In this article, Edward and his students explain how they measure the maximum tension in a pendulum string and compare the results to the theoretical model. The Vernier Idea Board is a place for teachers and students to post ideas on how to use Vernier products that might be useful to others. Go to the Discussion Board.
