Practise explaining how centre of gravity, base area and load position affect the stability of objects using CAIE IGCSE Physics questions and mark schemes.
A radio transmitter is a very tall, thin cylinder. It is prevented from falling over by wires which have one end fixed to the transmitter and the other end fixed in the ground. The ends of the wires in the ground are a long distance from the transmitter.
Fig. 4.1 shows the transmitter and two of the wires.
Fig. 4.1
The centre of gravity G is shown on Fig. 4.1.
Explain why the radio transmitter without the wires is a very unstable structure.
