Draw the Isometric view or projections of the following figure. Wired Isometric View 3d Isometric View

Draw a Plain Scale 1 cm = 1 m to Read Decimeters, to measure maximum distance of 6 m. Construction Steps:- 1) Calculate R.F. = Dimension in Drawing / Actual Dimension R.F. = 1 cm/ 1 m = 1/100 Length of scale             = R.F. X max. distance = 1/100 X 600 cm = 6 cms 2) Draw a…

Definition Representative Factor or Representative Fraction (R.F.) is defined as ratio of size or dimension of element or part in drawing to the size of same element or part of the actual object. Representative Factor (R.F.) = Dimension in Drawing / (Actual) Dimension of Object = Length or Width or Height in Drawing / (Actual) Length or Width…

·                     A cycloid is a curve generated by a point on the circumference of the circle as the circle rolls along a straight line with out slipping.. ·                     The moving circle is called the “Generating circle” and the straight line is called the “Directing line” or the “Base line”. ·                     The point on the Generating circle which generates…

·                     The cycloid is called the epicycloid when the generating circle rolls along another circle outside(directing circle) ·                     The curve traced by a point on a circle which rolls on the out side of a circular base surface CONSTRUCTION OF EPICYCLOID ·                     Step1: Draw and divide the circle in to 12 equal divisions. ·                     Step 2: Transfer the 12…

construction of hypocycloid ·                     The curve traced by a point on a circle which rolls on the inside of a circular base surface. ·                     Step 1: Divide the rolling circle in to 12 equal divisions. ·                     Step 2: Transfer the 12 divisions on to the base surface. ·                     Step 3: Mark the 12 positions of the circle – center…

CONIC SECTION mainly consists of three major parts they are Ellipse Parabola Hyperbola Conic sections are the intersections of a right regular cone, by a cutting plane in different positions, relative to the axis of the cone. PARABOLA The parabola  is a conic section, the intersection of a right circular conical surface and a plane to…

The parabola  is a conic section, the intersection of a right circular conical surface and a plane to a generating straight line of that surface. Given a point (the focus) and a corresponding line (the directrix) on the plane, the locus of points in that plane that are equidistant from them is a parabola OR SIMPLY…

A parabola is a curve traced by a point, moving such that, at any position ,its distance from the fixed point  (focus) is always equal to its distance from a fixed straight line (directrix)   parabola can be constructed in many ways.. like eccentricity method,  triangle method, oblong or rectangle method etc….  Triangle method triangle method of…
