Unformatted text preview: the same amount of force on the car. If the bridge is not moving it is in equilibrium and all the forces will add up to zero. Hooke’s Law Hooke’s law states that Fs = kx (where Fs is the force of the spring, k is spring constant and x is the amount the spring is stretched or compressed). Materials follow Hooke’s law to a certain extent. As materials follow this law they go back to the original shape when the force is done being applied. A graph of F vs. x would be a direct relationship. Each material will reach a certain yield position where it will no longer go back to the original shape. Shortly after this the material will break....
