Use the ideas of stability and centre of mass to explain the following. Double-backer buses have heavy weights attached to their undersides.

Double-dacker buses have heavy weight attached to their undersides to lower the centre of mass. If an object is tilted it will topple over if a vertical line from its centre of gravity falls outside its base.

Use the ideas of stability and centre of mass to explain the following. The crane has a heavy concrete block attached to one end of its arm, and others placed around its base.

The crane has a heavy concrete block attached to one of its arm to balance the load carried by its arm. Heavy weight are placed around its base to lower its centre of base and increase its area of contract thus making it more stable. Swinging the superstructure over the side when the outriggers are retracted, checkthe load chart for backwards stability.

The diagram shows the forces acting on a cyclist. Look at part b of the diagram. Are the forces on the cyclist balanced now ? How can you tell ?

The following forces are acting on the cyclist: (1) The weight of the cycle and the man acting vertically downwards through its centre of gravity. (2) The normal reaction equal to the weight of the system acting vertically upwards. (3) The force of friction working towards the centre of the curved path. (4) The outward centrifugal force opposite and equal to this force. Under these condition the cyclist is in equillibrium
