Question

the plane perpendicular to neutral surface is called​

Answer 1

In mechanics, the neutral plane or neutral surface is a conceptual plane within a beam or cantilever. ... Any line within the neutral plane parallel to the axis of the beam is called the deflection curve of the beam.

Answer 2

Constant Perpendicular Force

Explanation:

• Normal forces are the plane perpendicular to natural surface. The normal force is one type of ground reaction force.
• In mechanics, the normal force is the component of a contact force that is perpendicular to the surface that an object contacts
• Normal force is directly a result of Pauli exclusion principle and not a true force, it is a result of the interactions of the electrons at the surfaces of the objects.
• Normal force is a contact force that makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.
