How To Draw Surface Development Of A Cone Bottom Opened Youtube This tutorial will guide you on how to draw surface development of a cone (bottom opened hollow). Imagine a cone being rolled around on a flat surface. the apex will remain in a fixed location, while the base will trace out a circular arc on the surface, with a length equal to the circumference of the cone's base. this generates the development for the cone, which is a sector of a circle with radius r and sector angle θ.
Development Of Surfaces In Engineering Drawing Cone 1 Youtube No. of levels nothing but no. of parts doing in height wise. it is the process of converting the whole cone into an equal no. of parts. this types of the cone are required when the large cone is fabricated and it is not possible to layout the cone in a single part due to limitations of raw material sizes or limitations of forming process. A cone of base diameter 40 mm and slant height 60 mm is kept on the ground on its base. an aip inclined at 45° to the hp cuts the cone through the midpoint of the axis. draw the development. solution refer fig. 16.10. 1. draw fv and tv as shown. locate the aip. 2. divide the tv into 12 equal parts and draw the corresponding lateral lines. An finally draw lines from every arc back to the center of the main development as shown in figure 8. we can disregard the top half of the main development as the equal divisions form your full cone development. note: if this cone was to be cut out of steel these lines from the circumference to the center are actually called press lines. 228 views, 12 likes, 0 loves, 2 comments, 1 shares, facebook watch videos from joat academy: how to draw surface development of a cone (bottom closed).
