Equilibrium on a Rough Horizontal Plane

Applied Mathematics — Second Secondary

Equilibrium on a Rough Horizontal Plane

Lesson summary

Lesson summary

  • Friction is a tangential force between two surfaces in contact, opposing the motion or the tendency to move.
  • In equilibrium F ≤ μs R, and at the limit F = μs R.
  • The angle of friction λ satisfies tan λ = μs.
  • On a horizontal plane R = W when there is no vertical force, and R = W − P sin θ when the force is inclined upwards.
