Clock

Introduction:

A Clock is a circular device provided with three hands viz. an hour hand, minute and second hand. The study of the clock is known as “horology”.

[ A basic structure of a clock with three hands ]

Structure of a Clock:

A clock is composed of 360 degrees and divided into 12 equal divisions. The angle between the consecutive divisions is obtained by dividing the total angle of clock 360° by the number of divisions i.e. 12.

[Twelve equal divisions of a clock]

# The angle between any two consecutive divisions = (360°)/12= 30°

[Angle divisions of a clock]

A close observation of a clock reveals that an angular space between any two consecutive divisions has further five more divisions. The area between the two divisions corresponds to a value of 5 minutes. Hence, diving the 30° by five will result in the angular value of a minute.

Angular value of a minute = (30°)/5= 6°

[Angular values of minutes]

The table given below demonstrates the angular values of the first ten minutes:

Minute(s)	Angular values
1	6°
2	12°
3	18°
4	24°
5	30°
6	36°
7	42°
8	48°
9	54°
10	60°
