CALCULATORS / MECHANISMS

Linkages and mechanisms

Planar rigid-link geometry with explicit joints and branches.

link lengths, input angle or motion → assembly branches, motion range, coupler path

crank radius, rod length, RPM → stroke, displacement, velocity, acceleration

link lengths, ground link, input rotation → Grashof classification, rocker sweep

link lengths, lift height, load, actuator attachment → actuator force, stroke, singular positions

link lengths, input force, terminal angle → clamp force estimate, travel, singularity

link geometry, input path → output path, motion scale, workspace

slot count, driver speed, pin geometry → index angle, dwell, engagement motion

tooth count, lever stroke, torque → index increment, pawl load

joint angle, input speed and phase → instantaneous output speed, ripple

beam geometry, modulus, desired rotation or displacement → stiffness, force, strain screening

mechanism pose, applied force or torque → instantaneous force and motion ratio

joint limits, link geometry, reference frame → reachable region, collision candidates
