Diagram 6 shows a poster of 1.2 kg hanging on a wall by a rope at an angle of 40° to the vertical.
What is the tension of the rope?
4.6 N
6.0 N
7.8 N
9.3 N
Diagram 7 shows a 10 kg load is suspended by two threads.
What is the tension of Thread 1?
50.0 N
64.0 N

Diagram 8 shows a box resting on an inclined plane at angle θ to the vertical.
There are three forces acting on the box. By using m for mass of the box, g for the acceleration due to gravity, and F for frictional force, derive an equation to express the frictional force of the box on the inclined plane.
F = mg sin θ
F = mg cos θ
F = mg tan θ
F = mg cos (90 – θ)
