Putlog holes or putlock holes [1] are small holes made in the walls of structures to receive the ends of poles (small round logs) or beams, called putlogs or putlocks, to support a scaffolding. [2] Putlog holes may extend through a wall to provide staging on both sides of the wall.
Stiffness depends upon material properties and geometry. The stiffness of a structural element of a given material is the product of the material's Young's modulus and the element's second moment of area. Stiffness is measured in force per unit length (newtons per millimetre or N/mm), and is equivalent to the 'force constant' in Hooke's Law.
The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
The term bent is not restricted to any particular material. Bents may be formed of wooden piles, timber framing, [17] steel framing, or even concrete. [18] Bistable structure – Brick – is building material used to make walls, pavements and other elements in masonry construction.
The elastic modulus of a material is not the same as the stiffness of a component made from that material. Elastic modulus is a property of the constituent material; stiffness is a property of a structure or component of a structure, and hence it is dependent upon various physical dimensions that describe that component.
A honeycomb-shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties. [1] Man-made honeycomb structural materials are commonly made by layering a honeycomb material between two thin layers that provide strength in tension. This forms a plate-like assembly.

Young's modulus is the slope of the linear part of the stress–strain curve for a material under tension or compression. Young's modulus (or Young modulus ) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise.
