First order lever
Science Park Models First Order Lever contains a bar which is supported at its stationary point or fulcrum as per its length wise. It is utilized to control the resistance at second point when a force is applied on it at a third point. Principle of a level is when two equal forces are applied on an uniform lever in reverse directions i.e. anti clockwise and clockwise, then the applied force generates a state of equilibrium on the applied lever. This science park equipment demonstrates several mechanical aspects of a first order lever having different fulcrum distances from weight. This product is suitable for students of 4rth, 5th and 6th standards.
