3.1 Torque

________ means it requires less effort, or less force to do something (e.g.

⬆️ torque

________ (r): the position vector from the pivot to the point where the force is being applied.

Radius

________ (AKA force arm) (r⟂ or d): shortest distance between pivot point and line of action.

Perpendicular distance

the line around which an object rotates (e.g

axis of rotation (pivot, pivot point, fulcrum)

the position vector from the pivot to the point where the force is being applied

radius (r)

an imaginary line extending out both ends of the force vector

line of action

shortest distance between pivot point and line of action

perpendicular distance (AKA force arm) (r⟂ or d)

⬆️ force = ⬆️ torque

the size of the applied force

⬆️ distance = ⬆️ torque

the perpendicular distance

⬆️ sinθ = ⬆️ torque

the angle between the applied force and lever arm (𝜃 sometimes ɸ)
