Dynamics: Analyzing forces in mechanisms, including turning moment diagrams and flywheel design. Given crank length r

  • Problem: In velocity/acceleration analysis, your drawn length doesn't match the solution.
  • Solution Check: Check

Example quick walkthrough (slider-crank velocity)

  1. Given crank length r, connecting rod length l, crank angle θ.
  2. Position of slider x = r·cosθ + sqrt(l^2 − r^2·sin^2θ).
  3. Velocity v = dx/dt = (dx/dθ)·ω. Compute dx/dθ analytically, then multiply by ω.
  4. Check endpoints: θ = 0, π/2 for sanity.
