An example of this type of system is a see saw. In a see saw, the children apply the two forces at the ends, and the fulcrum in the middle gives the counter force to maintain the see saw in a neutral position. Another example are the major vertical forces on an airplane in flight. == References == Kumar, K.L. (2003). Engineering Mechanics,3e (in Dutch). McGraw-Hill Education (India) Pvt Limited. p. 90.
