A room of 1728 m3 volume is shown by a cube of 216 cm3 volume. Find the RF & Construct a plain scale to measure up to 42 m. Mark a distance of 22m on this scale
Sol) Given data:
RF = 3 (216) cm3/ (1728 x (100)3) cm3
= 1/200.
Max Length (ML) = 42 m (6 x 7 or 7 x 6); LOS is divided into 6 parts of 7 m each or 7 parts of 6 m each
Length of scale (LOS) = RF X ML (in cm) = (1/200) x 42 x 100 cm (1 m=100cm) = 21cm.
The length of the line that is drawn on the drawing sheet is 21 cm.
The sub scale is to be divided into 6 or 7 parts.
The length to be shown is 22 m = 18 m (on main scale) + 4 m (on sub scale)
