Question: a linear spring k is restricted so that it can...

Question details

A linear spring k is restricted so that it can move only vertically, as shown in the figure. A massless link of length L has one hinged at the end of the spring and a point of mass m attached at the other end.

  1. Identify possible set of generalized coordinates describing the motion.
  2. Write the potential and kinetic energy expression
  3. Derive Lagrange’s equations of motion about the equilibrium position. Assume small motions.
