9M603.56*RecapIn previous class, we have reviewed about

Elements of cost , Depreciation and related problems,Estimation procedure Difference between estimation and costing

9M603.56
9M603.56*ObjectivesOn completion of this period you will be able to know Procedure for estimation of weights of materials.calculation of areas and circumference of SquareTriangleTrapeziumRectangleParallelogramCircleOther such standard geometric figures

9M603.56
9M603.56*Procedure for estimation of weights of materialsBreak up the component drawing into simple and meaningful parts.Calculate the volume of each individual part making use of mensuration formulae.Small fillets and rounded corners may be neglected.Add all these volumes to get total volume of component.Multiply the volume by density of material .Account for scrap and wastage.Weight of material is multiplied by cost per unit weight of material to arrive direct material cost.

9M603.56
9M603.56*Areas Of Plane Figures Rectangle: l=Length of rectangle b=Breadth of rectangle Then, Area = l x b Perimeter = 2(l + b)

9M603.56
9M603.56*Square Let, S = Length of each side of square d = Length of diagonal

Then, Area = S2 or d2 / 2 Perimeter = 4S

9M603.56
9M603.56*Parallelogram l = Length of one side of Parallelogram b = breadth of another side of Parallelogram h = Height of ParallelogramThen, Area = l X h Perimeter = 2(l+ b)

9M603.56
9M603.56* Triangle let a, b and c are lengths of the sides of a triangle. h = height of `A` from base BCThen, Area = a x h = x Base x Perpendicular height Perimeter = a + b + c and S = (a + b + c)/2 Then, Area =

9M603.56
9M603.56*Hexagon : Let, a = length of each side of Hexagon h = heightThen, Perimeter = 6a Height h = 3 a Area = (3 3/2)a2

9M603.56
9M603.56*Any Regular Polygon :

General formula for any regular polygon having `n sides of length `a` units each are : Perimeter = n.a Area = perimeter x inner radius

9M603.56
9M603.56*Trapezium : Let a, b, c, and d are the lengths of four sides. h = Perpendicular distance between parallel sides Perimeter = a + b + c+ d Area =

9M603.56
9M603.56*Circle :Let r = radius of circle d = Diameter of circle

Area =

=

Perimeter = d = 2 r

9M603.56
9M603.56*Sector : Let r = radius of circle = Angle in radians l = Length of arc l = r

Area = (Angle of sector/(2 )) X Area of circle = =

9M603.56
9M603.56*Fillet (Circular) : Let r = radius of fillet. Then, Area of fillet = r2 - /4 r2 = r2(1 - /4 r2) = 0.215r2 = r2(approx)

9M603.56
9M603.56*Ellipse : Let a = semi major axis. b = semi minor axis Area = ab Perimeter = (a + b)

9M603.56
9M603.56*Segment of a circle : Area = Where h = BD l = AC

9M603.56
9M603.56*SUMMARYWe have discussed about calculation of various areas of

SquareRectangleParallelogramTriangleHexagonTrapeziumCircleSector

9M603.56
9M603.56*QUIZ1. Area of the ellipse a) Area = ab b) Area = (a+b) c) Area = /ab d) Area = (a-b)

9M603.56
9M603.56*2. Area of circular fillet a) 0.215r2 b) 0.150r2 c) 0.225r2 d) 0.250r2

9M603.56
9M603.56*AssignmentWrite the procedure to be followed for estimating direct material cost.Write down the formulae for areas ofEllipseFillet SectorRegular polygonSegment of circle
