Fig. 2-13: Inclined display unit

Fig. 2-13 shows an inclined display unit. The centre of mass of the unit is outside the base of the unit as shown in Fig. 2-13a. To make the unit stable and prevent it from overturning, a support base is fixed to the lower part of the display unit (Fig. 2-13b). The added base effectively increases the size of the base of the unit to ensure that the centre of mass of the display unit will be above the area of the new base of the unit. Thus the inclined display unit becomes stable. Other safety measures are also applied to ensure that the display unit is stable.
