Integrable systems and chaos A mechanical system is said to be integrable if its equations of motion are soluble in the sense that they can be reduced to integrations. (You do not need to be able to evaluate the integrals in terms of standard functions.)
A theorem due to Liouville states that any Hamiltonian system with n degrees of freedom is integrable if it has n independent constants of the motion, and all these quantities commute in the sense that all their mutual Poisson brackets are zero.
The qualitative behaviour of integrable Hamiltonian systems is well investigated (see Goldstein [4]). In particular, no integrable Hamiltonian system can exhibit chaos.
Use Liouville's theorem to show that any autonomous system with n degrees of freedom and n - 1 cyclic coordinates must be integrable.

When the part is made from 4320 steel, the hardness is only HRC 32. Determine the hardness if the part were made under identical conditions, but with the following steels. Which, if any, of these steels would be better choices than 4320?
A certain part is routed through six machines in a batch production plant. The setup and operation time' for each machine are given in the table below. The batch size is 100 and the average non operation time per machine is 12 hr.
Calculate the operational availability for a power generator with 1 scheduled maintenance per 1000 hours of operation and failure rate of 0.6 failures per 1000 hours.
A storm with winds of 30 mph deposits 16 in. of snow having a specific weight of 5.0 lbf/ft3. A1/2 size scale model is to be used to investigate the effectiveness of a proposed snow fence. If the air density is the same for the model and the stor..
A solid with Young's modulus E = 70 GPa and Poissonâ's ratio = 0.3 is in a state of plane strain parallel to the xy-plane. The in-plane strain components are measured as follows: Epsilon-xx = 0.007, epsilon-yy = -0.008, and epsilon-xy = 0.02. Compute..
