CHAPTER 9:

STABILITY

STABLE An object is said to be stable if it does not

topple (jatuh) easily.

AB

CENTRE OF GRAVITY Centre of gravity= point of equilibrium Centre of gravity= is the point at which

whole weight of the object may be considered to act.

The position of the centre of gravity of an object depends on the shape of the object.

FACTORS AFFECTING THE STABILITY OF OBJECT

A BA B

QUESTIONS Which of the following objects is the most

stable?

A CB

QUESTIONSHow can make this chair more stable?

Answer…

Reducing the height of chair ( Lower the centre of gravity)

Large the base Area

IMPORTANCE OF STABILITYA race car is heavy, has a low centre of gravity and a

large base area

Chairs and tables are

objects with a low centre of gravity and wide base.
