Typical exercise types and how to approach them

  1. Link classification and inversion

    • Read mechanism diagram, label links and joints.
    • Apply Grashof criterion: s + l ≤ p + q (identify shortest s and longest l).
    • Decide possible inversions and mobility (Kutzbach criterion if needed).

  2. Velocity and acceleration (instant center and analytical)

    • For planar linkages, first locate instantaneous centers (ICs) for velocity diagrams.
    • Use relative velocity v = ω × r or v = ω·r (perpendicular magnitude).
    • For acceleration, break into tangential and normal components: at = α·r, an = ω^2·r.
    • When multiple links interact, write vector loop equations and differentiate.

  3. Displacement analysis (slider-crank, 4-bar)

    • Set up loop-closure geometric equations (cos/sin form).
    • Solve algebraically or use numerical root-finding (Newton–Raphson) when needed.
    • For repeated tasks, create a small script (Python/Octave/Matlab) to compute positions over a crank rotation.

  4. Cams

    • Draw displacement vs. cam angle; choose motion law (simple harmonic, cycloidal, constant acceleration).
    • Differentiate to get follower velocity and acceleration.
    • Construct profile using offset and pressure angle limits; check for undercut.

  5. Gear trains

    • Convert gear pairs to velocity ratio i = -N_driver/N_driven.
    • For epicyclic trains use relative-motion method or tabular approach for teeth counts and arm rotations.
    • Check contact ratio and avoid interference for practical design.

  6. Flywheels

    • Compute required moment of inertia I to limit fluctuation Δω for given energy pulsation ΔE: ΔE = 0.5·I·(ω_max^2 − ω_min^2).
    • Use approximate formula: I = ΔE/ω^2 for small fluctuations.

  7. Governors

    • Derive equilibrium relation between speed and sleeve radius.
    • Compute speed sensitivity and plot governor characteristic.
    • Check for hunting using natural frequency approximation.

  8. Balancing

    • For rotating masses, ensure Σm·r = 0 in the plane for static balance; use counterweights or balance masses.
    • For dynamic balancing of multiple masses in different planes, set up equations for Σm·r·cosθ and Σm·r·sinθ and moments about center.
    • For reciprocating masses use equivalent rotating mass m_eq = M·(stroke)/(2·π) approximation for preliminary balancing.

  9. Vibrations

    • For m–k system, natural frequency ω_n = sqrt(k/m).
    • For damped systems, classify underdamped/critically damped/overdamped by ζ = c/(2·√(km)).
    • For forced vibration, compute steady-state amplitude and resonance criteria.
