where the load goes
Concept

Elasticity — where it appears

The property of returning to the original shape when a load is removed, and the theory built on it in which stress is a linear function of strain. It is the assumption under every section calculation in this collection, and the region within which superposition is available.

The hole that multiplies the stress by three

The stress at the side of a hole is three times the applied stress whatever the hole's size, and at the top and bottom of the same hole it is minus one times it — compression in a plate that nothing is pushing.

How far a wrong load reaches

Every figure in this collection applies a load as a point, a line or a uniform pressure, and no real load is any of those. The licence is Saint-Venant's, it is usually quoted as a principle, and it is really a statement about a wavelength.
