1. Hey! i have done a physics lab on cantilevers, and what i did was i varied the length of the leaver while keeping the force applied constant and measured the displacement down of the leaver. However, i am not sure what to graph and what formula i should be using as we have not done cantilevers in school (this is a design lab and we can investigate anything).
2. i calculated the spring constant (k) for each of the different lengths by using f=-kx but I'm not sure if that is the right formula to use. i have graphed (length of leaver)^2 VS. Displacement but i am not sure what the gradient is equal too. And i tried graphing the Length of leaver VS. K that i calculated but i get an exponential and have no clue what the gradient is equal too.
It would be very helpful you someone could please point me in the right direction!
