Representative fraction (R.F.) C. Graphical scale : To draw a scale, need to know the “Representative Factor (RF)”. 0000011920 00000 n Ans37:-The ratio of the drawing size of an object to its actual size is called the Representative fraction. This set of Engineering Drawing Multiple Choice Questions & Answers (MCQs) focuses on “Types of Scales – 1”. 0000003961 00000 n Engineering Drawing is one of the basic courses to study for all engineering disciplines. Representative Fraction (R.F) : It is the ratio of the distance on the map to the corresponding distance on the ground taken as same units. Explanation: Representative fraction is the ratio of the length of the object represented on drawing to the actual length of the object represented. Q37 – What is the representative fraction (R.F.) Understanding Scale and Representative Fraction . The primary problem faced in learning and teaching of engineering drawing is the limited availability of text books that focus on the basic rules and of scale is always A) Less than 1 B) Equal to 1 C) Greater than 1 D) Any of these 6 The unit of R.F. Scales: Representative fraction. A. v actual volume b dimensions of large objects must be reduced to accommodate on standard size drawing sheet.this reduction creates a scale of that reduction ratio, which is generally a fraction.. such a scale is called reducing scale and that ratio is called representative factor. A representative fraction of 1:0.2 means 5:1, i.e. Or it is also called Scale factor. is A) Cubic centimeter B) Square centimeter C) Centimeter D) None of … 0000015891 00000 n The actual length of the object / Length of an object in the drawing B.

This means, 1 cm on the drawing represents 10 m on the ground, the scale of the map is 10 m to 1 cm.

There is a ‘Representative fraction’ (RF) and it is defined as? Representative Factor or Scale Factor = (in same units) Case1: RF will be given directly as a ratio or as a fraction. 0000002135 00000 n Hence the scale is enlarging scale. Plain scale construction in engineering drawing - Duration: 20:39. Representative fractions are expressed in the form of 1 followed by a : (colon) and then a number, where the one is the numerator in the fraction, the colon represents the division operation, and the other number is the denominator. x max. Invert the fraction and multiply by 12 to get: 4/1 x 12 = 48; Your scale factor is 48; For calculating the scale factor from an engineering drawing scale, only multiply the feet by 12. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies. 0000001374 00000 n .
