Answer:
Difference between single plane method and double plane method:-
A tetrahedral wedge of shake can slide on either of the jumping irregularity surfaces. The test to recognize these two components can be performed on a stereograph dependent on the direction of the two discontinuities, their line of convergence and the incline face.
An option stereographic technique includes recognizing the incredible hover, known as a π-circle, connecting the brokenness shafts and contrasting this plane and the incline face direction. A kinematically plausible wedge is twofold plane sliding except if the accompanying two criteria are met.
1) One of the posts is inside the light envelope for the incline face and 2) that shaft lies between the plunge bearing of the π-circle and the course inverse to the slant heading of the removal face. These criteria are promptly discernible on a stereograph.
The limits for shafts equipped for framing single and twofold plane sliding wedges in blend with another post can be set apart as zones on the stereograph.
