= the net work input to the mechanism, that is, the work input less the work output = the change in the kinetic energy of the moving links = the change in the potential energy stored in the mechanism = the energy dissipated through damping and friction Kinetic Energy The time rate of change of the kinetic energy can be written from Chapter 15 in the text book as Where the generalized inputs for this problem are ? = θ 2 , = ω 2 , and = α 2 . Therefore, the time rate of change of the kinetic energy for this problem can be written as To determine . Note that , (i.e., the equivalent mass moment of intertia) therefore, the units must

Note that , therefore, the units must be lbs-ft-sec 2 . For link 4. For link 5. Therefore, the sum of the coefficients is Potential Energy For this problem, the potential energy is related to gravity effect only. The time rate of change potential energy term due to gravity effects can be written as For link 4. For link 5....
