c) Couples and torques

• define couple

• a pair of equal (in size) and opposite (in direction) parallel forces

• → on opposite sides of an object

• → that causes the object to rotate without translating

• define torque

• the moment of a couple

• state the formula for the torque of a couple

• T = Fd

  • torque of a couple (Nm) = magnitude of one of the forces (N) × perpendicular distance between the two forces (m)

• n/a

• n/a
