- This is represented in
**crosssection**and in position in fig. - Igneous intrusions consist only of unimportant dikes of trap. The most striking and uniformly characteristic geologic feature of the mountains is their internal structure, consisting of innumerable parallel, long and narrow folds, always closely appressed in the eastern part of any
**crosssection**(Piedmont Plateau to Great Valley), less so along a central zone (Great Valley and Valley Ridges), and increasingly open on the west (Allegheny and Cumberland Plateaus). - A, B, Line along which the
**crosssection**C of the plate is taken. - In the case, therefore, of any solid whose cross-section at distance x from one end is a quadratic function of x, the position of the
**crosssection**through the centroid is to be found by determining the position of the centre of gravity of particles of masses proportional to So, S2, and 4S 1, placed at the extremities and the middle of a line drawn from one end of the solid to the other. - Let S be the area of the
**crosssection**at distance x from the plane A.
