To insure that the belt tension is sufﬁciently high to avoid zero tension in the belt edges at a concave curve, a check of the curve radius should be made by the use of the following formula for fabric constructions: (2)

### Egg Curves and Ovals - Mathematische Basteleien

An oval is a closed plane line, which is like an ellipse or like the shape of the egg of a hen. An egg curve only is the border line of a hen egg. The hen egg is smaller at one end and has only one symmetry axis. The oval and the egg shaped curve are convex curves, differentiate twice and has a positive curvature.

### Difference between Convex and Concave Curves | Convex vs ...

Difference between Convex and Concave Curves. Tweet. Key Difference: A concave curve is rounded inward, whereas a convex curve is rounded like the exterior of a sphere. A curve is very different from a straight line. A curve has a varying slope. It is a wiggly line or bent line which wiggles or bends to join any two points on a graph or a map.

### #16 Conveyor Belt Modulus of Elasticity
