Forces and equilibrium

Rigid-body, quasistatic equilibrium.

force, arm length, included angle → torque or required force

lever arms, applied force → output force, travel tradeoff

loads, load positions, supports → support forces and moments

load, sling angles, number of legs → leg tensions, angle sensitivity

mass, slope, friction coefficient → push or pull force, normal reaction

normal force, friction coefficients → breakaway and sliding force

center of mass, footprint, external load → tipping threshold, restoring moment

load, lever arms, acceleration allowance → counterweight mass, residual torque

reeving, load, pulley efficiency → pull force, rope travel

disturbance load, friction, clamp geometry → required preload, slip margin

force, contact area → average pressure, load distribution assumption

wedge angle, friction, load → input force, output travel, release condition
