Construct a Diagonal scale of RF = 3:200  showing meters, decimeters and centimeters. The scale should measure up to 6 meters. Show a distance of 4.56 meters

• Length of the scale  =  (3/200) x 6 m  = 9 cm
• Draw a line AB = 9 cm . Divide it in to 6 equal parts.
• Divide the first part A0 into 10 equal divisions.
• At A draw a perpendicular and step-off along it 10 equal divisions, ending at D.

Diagonal Scale

 

• Complete the rectangle ABCD.
• Draw perpendiculars at meter-divisions i.e. 1, 2, 3, and 4.
• Draw horizontal lines through the division points on AD. Join D with the end of the first division along A0 (i.e. 9).
• Through the remaining points i.e. 8, 7, 6, … draw lines // to D9.
• PQ = 4.56 meters
