• Analyse the forces, is the box stationary or
  moving
• Choose an axis
• Calculate the forces
• Sine Rule, the triangle must consist of the
  forces

• A cart of mass 10kg held at rest on an inclined
  plane of 30o by a force F. The coefficient of
  static friction between the cart and the incline
  is µs 0.3. Calculate the magnitude of F.
