It is the SI unit of a force required to give a mass of 1 kg an acceleration of 1 m/s2 and is equivalent to 100,000 dynes

It is the strength of the structure that resists the external applied forces. It is also the pressure or tension exerted on a material object. NSCP defines it as force per unit area

What stress is developed when the force applied tends to shorten the structure

A hinge support has two reaction components for 2 dimensional axis; how may reaction components for 3-dimensional axis.

The distance between two structural supports of a roof truss is called span length. What do you call the spacing between trusses

Why is it the long-spanned trusses are cambered

These structure are generally compressed, as such, they are considered "compression members"

The angle between the total reaction and the normal force when limiting friction is acting is called?

1. Newton (N) is the SI unit of Force and was named after Isaac Newton in recognition of his contributions to the field of Mechanics. It is denoted by N and is expressed in 

1. A type of stress developed when the force applied tends to elongate the structure.

The deformation of a material from stress. It is simply a ratio of the change in length to the original length.

1. This Law states that “the stress is proportional to strain”.

The distance between two structural supports is called:

What is the purpose of the truss?

The _____ oof a body is the point where there is equal volume on all sides. For a solid body made from a single material it is the center of its mass

For a force system to be in equilibrium, the algebraic sum of acting and reacting forces must be:

They are forces whose lines of action meet at a common point

Law of equilibrium condition: " For every action, There is an equal and opposite reaction."

It is the ratio of the stress in a body to the corresponding strain (as in bulk modulus and shear modulus). It is also called Young's modulus.
