GCSE Questions: Moments and Centre of Gravity
Q6. The diagram shows a fork-lift truck lifting a heavy crate.
(a) The crate weighs 11 500 N and is lifted vertically 2.60 m.
Calculate the work done to lift the crate.
(b) The weight of the crate causes a clockwise moment of 13 800 Nm about the centre of the front wheel of the fork-lift truck.
The weight of the fork-lift truck and driver cause an anticlockwise moment.
What is the minimum size of the anticlockwise moment needed so that the fork-lift truck does not topple over?
