2) A television is held onto a wall by two brackets, as shown.

Which diagram correctly shows the forces on the television from the brackets.

3) A light uniform metre rule is held horizontal by two strings which have tensions T₁ and T₂. Two forces of 25 N and 70 N act at the 15 cm and 75 cm marks respectively. What is the magnitude of T₁ and T₂?

4) A 1 m long uniform beam of weight 6 N is being lifted by a vertical force, F, at the 0.75 m mark.

What if the minimum force, F, that will lift the beam?

5) A ball rests against a step. A force, F , is applied in an attempt to rotate the ball up the step.

Which force would not be able to create a moment able to rotate the ball up the step?
