This document discusses planes and their projections. It defines a plane as a flat, two-dimensional surface with infinite width and length but no thickness. Planes can be divided into two main types: perpendicular planes and oblique planes. Perpendicular planes are perpendicular to one of the principal planes of projection, while oblique planes are inclined to both principal planes. The document shows various positions of perpendicular planes, including ones that are parallel or perpendicular to the horizontal and vertical planes, or inclined to one and perpendicular to the other.
Projections of Planes : Lect 01
- 1. Unit No:04 Projections of Planes Yash B. Parikh M.Tech. (CIM) Assistant Professor Department of Mechanical Engineering Symbiosis Institute of Technology
- 2. 2 What is a Plane? Prof. Yash Parikh
- 3. 3 What is a Plane? In mathematics. a plane is a flat, two-dimensional surface. It can also defined as an abstract surface which has infinite width and length, zero thickness, and zero curvature. Prof. Yash Parikh
- 4. 4 Introduction A Plane is a two dimensional entity having only length and breadth with negligible thickness (which is considered as zero). Prof. Yash Parikh
- 5. 5 Shapes of Planes Prof. Yash Parikh
- 6. 6 Types of Planes Planes may be divided as two main types. They are : (I) Perpendicular Planes (II) Oblique Planes. (I) Perpendicular Planes : Planes which are perpendicular to any one of the principal planes of projection are called as perpendicular planes. These planes may be inclined or parallel to the other principal plane. Prof. Yash Parikh
- 7. 7 Types of Planes (II) Oblique Plane : Here Planes are inclined to both the reference planes. Projections of such planes are drawn in three stages. Prof. Yash Parikh
- 8. 8 Various Positions of Perpendicular Planes (a) Plane is Perpendicular to V.P. & Parallel to H.P. Prof. Yash Parikh
- 9. 9 Various Positions of Perpendicular Planes (b) Plane is Perpendicular to H.P. & Parallel to V.P. Prof. Yash Parikh
- 10. 10 Various Positions of Perpendicular Planes (c) Plane is Perpendicular to both H.P. & V.P. Prof. Yash Parikh
- 11. 11 Various Positions of Perpendicular Planes (d) Plane is inclined to H.P. & Perpendicular to V.P. Prof. Yash Parikh
- 12. 12 Various Positions of Perpendicular Planes (e) Plane is inclined to V.P. & Perpendicular to H.P. Prof. Yash Parikh
