Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
A cross section is formed.
Yes the triangular cross-section area is congruent throughput the prism.
add up the cross section and see what vthe answer is, then times it by the other part. Simple!
It is a triangle.
Introduction of Arches reduces the bending moment at cross sections due to presence of horizontal force at the support whenever bridge is loaded and thus requirement of cross section is lesser. When triangles are easy to propagate and can have tension/compression only if used as 2-point member in bridges (forces acts only the end of any member not in between), Due to absence of bending moment it also reduces the cross-section requirement. Therefore, if we introduce arches and triangles cross section requirements of each small member get reduced.
In Geometry, cross-section is the shape made when a solid is cut through by a plane. The cross section of a circular cylinder is a circle. * * * * * There are also cross-sections that are ellipses or rectangles.
A thrust diagram refers to a cross-section diagram that shows how a thrust fault is formed.
No, it is not. Its cross section gets smaller as you go up.
A. Circle just did it on apex!
