Represent the number of inhabitains in five cities of a country by bar chart (horizontal bar diagram):

A horizontal bar fixed rigidly at one end is called a cantilever. When a load is hung at its free end the cantilever (i) bends (ii) inclines at an angle with the horizontal without bending .What will be the nature of strain in each case?

What is histogram? How does it differ from a bar diagram?

Represent the data in the adjacent bar graph as frequency distribution table.

A bar of length l carrying a small mass m at one of its ends rotates with a uniform angular speed omega in a vertical plane about the mid-point of the bar. During the rotation, at some instant of time when the bar is horizontal, the mass is detached from the bar but the bar continues to rotate with same omega . The mass moves vertically up, comes back and reaches the bar at the same point. At that place, the acceleration due to gravity is g.

Diameter of a circular conducting coil 20 cm and the number of turns in it is 500 . If 3 a current is sent through it , the strength of the coil becomes equal to the strength of a bar magnet of length 5cm . Determine the pole - strength of the bar magnet .

Represent the following data by a pie chart on proposed outlay during a Five-year plan of a Government:

In a city three daily newspapers X,Y,Z are published, 65% of the citizens read X, 54% read Y, 45% read Z, 38% read X and Y, 32% read Y and Z, 28% read X and Z , 12% do not read any one of these three papers. If the total number of people in the city be 1000000 find the number of citizens who read all the three newspapers. [You may use a Venn diagram or a standard formula for the enumeration of elements of sets.]

The number of students in university during 1995-98 is given below: Represent the information cotained in the above table by component bar chart.
