scale drawings

An artist drew a picture of a giant wheel and the scale he used was 1 inch : 6 feet. If the diameter of the giant wheel measured 19 inches on his drawing board, then find the actual diameter of the giant wheel. => 114 feet or 115 feet or 113 feet or 116 feet..

Henry wanted to draw a picture of a 100 m tall transmitting tower on a hillock of height 400 m. The combined length of the hillock and the tower on the paper is 10 cm. Find the scale Henry used. => 1 cm : 50 m or 1 m : 50 cm or 2 cm : 50 m or 2 m : 50 cm..

Question 1 - Question: By taking scale 1cm=10% draw a histogram of the following data: Answer: The required histogram representing the given data is shown in grap..

Distance between parallel lines: Draw two lines along the two edges of a scale. You get parallel lines (l and m). Let l || m. ..

(i) We plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequencies, (10, 2), (20, 10), (30, 22), (40, 40), (50, 68), (60, 90), (70, 96) and (80, 100) are the coordinates of the points. (ii) Join the points plotted by a smooth curve. (iii) An Ogive..

The position of the point P in a plane in the rectangular co-ordinate system is determined as follows: Draw PA and PB perpendicular to XX' and YY'. The segment OA = a measures the distance along the x-axis (the x-coordinate and the perpendicular distance AP = OB = b ( parallel to y - a..

Melde's Experiment - Melde's electrically maintained tuning fork consists of a large tuning fork (F) made of a ferromagnetic alloy, whose shank is rigidly clamped to a heavy rectangular wooden board (W). A bent strip of a metal is attached to one of the prongs of the fork and this serves as a sprin..

. Consider any two points A and B on the straight-line graph. Draw perpendiculars from A and B to x and y-axes. Join A to C, ACB forms a right-angled triangle. Calculations Write the title and scale chosen for the graph. Let us now see the nature of the v - t graph for the diffe..

Analyse the given data and make a proper choice of scale for time and distance. Plot the points. Join the point..
