INTERSECTION OF SOLIDS

WHEN ONE SOLID PENETRATES ANOTHER SOLID THEN THEIR SURFACES INTERSECT AND AT THE JUNCTION OF INTERSECTION A TYPICAL CURVE IS FORMED, WHICH REMAINS COMMON TO BOTH SOLIDS. THIS CURVE IS CALLED CURVE OF INTERSECTION AND IT IS A RESULT OF INTERPENETRATION OF SOLIDS. PURPOSE OF DRAWING THESE CURVES:- WHEN TWO OBJECTS ARE TO BE JOINED TOGATHER, MAXIMUM SURFACE CONTACT BETWEEN BOTH BECOMES A BASIC REQUIREMENT FOR STRONGEST & LEAK-PROOF JOINT. Curves of Intersections being common to both Intersecting solids, shows exact & maximum surface contact of both solids.

COMMON SOLUTION STEPS

  • One solid will be standing on HP
  • Other will penetrate horizontally.
  • Draw three views of standing solid.
  • Name views as per the illustrations.
  • Beginning with side view draw three Views
  • f penetrating solids also.
  • On it’s S.V. mark number of points And

name those (eitherletters or nos.)

slide-5
SLIDE 5
  • The points which are on standard

generators or edges of standing solid, ( in S.V.) can be marked on respective generators in Fv and Tv. And other points from SV should be brought to Tv first and then projecting upward To Fv.

  • Dark and dotted line’s decision should be

taken by observing side view from it’s right side as shown by arrow.

  • Accordingly those should be joined by

curvature or straight lines.
