    Time-Dependent Lagrangians: Reference Work & Euler-Lagrange Equations

    I'm looking for a good reference work on time-dependent Lagrangians. For example, the Lagrangian and resultant Euler-Lagrange equations for a forced harmonic oscillator. All the classical textbooks just skip over this subject area. Obviously the system is non-energy conserving. In deriving...

    Coupling multiple engine onto one drive shaft

    No skill is needed to couple two engines together. A V8 is essentially 8 one-cylinder engines tied together. Large ship engines come in 4,6,8,10,12,14,16 cylinder versions. Several auto companies, including Renault and Audi, have built 'W' engines by chaining together two V-4 engines. The...
