Types of Cubic Curves are:
1.Bezier Curves
2.B-Splines
3.NURBS (Non-uniform Rational B-splines)
A parametric cubic curve is a cubic curve made up of two equations. For example an x(t) part, and a y(t) part. They may also be known as 'Bezier' curves. Parametric equations are generally controlled by a 't' value. A google search of 'parametric cubic' may also give you some more information.

Cubic units are used to measure 3-Dimensional objects. The cubic(x to the third power) units are used to demonstrate the 3 dimensions.
it can do but when you get an erection its normal for it to curve in any direction

Based on the given problem,parabolic and cubic curves are drawn in SFD and BMD.if the given problem has UDL(uniformly distributed load),then we get parbolic curve in BMD.if the given problem contains UVL(uniformly distributed load),then we get parabolic curve in SFD and cubic in BMD.

Derviative of function is also important.So it does not guarantee a desired curve,which might have bumps.

Any 4 points in the Cartesian plane determine a unique equation that is of degree at most three (i.e., a "cubic" equation). It is, of course, possible that the 4 points actually lie on a degree two ("quadratic"), a degree one ("linear"), or a degree zero ("constant") equation. However, if the 4 points do not lie on a constant, linear, or quadratic curve, then they will like on a unique cubic curve. In general, N points will determine a unique curve of degree at most (N-1).
Convex lenses are curved inward. Concave lenses curve outward.
