an influence or action on a body or an object that either makes or attempts to make it move, change position. Force is measured in Newtons (N), or kilonewtons(kN)
1 of 15
Magnitude
the size of the force
2 of 15
Direction
the specific line of action of the force
3 of 15
Mass
the amount of matter in an object and is measured in grammes or kilogrammes.
4 of 15
Density
a characteristic of materials and is a measure of the mass per unit of volume.
5 of 15
Weight
the force exerted by a mass due to gravity.
6 of 15
Moment
a force that acts a perpendicular distance from a particular point, the effect of the moment is to cause the point about which it acts to rotate or to try and resist rotation.
7 of 15
Pressure
a measure of the intensity of force applied to the surface of an object.
8 of 15
Stress
a measure of the intensity of force within a structural element.
9 of 15
Strain
is complimentary to stress, it is a measure of a materials response to stress.
10 of 15
Bracing Element
an element which is provided solely for stability and which does not contribute directly to resisting the principal load
11 of 15
Dear Load
The weight of the structure and building itself, floors, walls and roof - always present
12 of 15
Live Load
Load produced by the use of the building, the people, furniture and etc.
13 of 15
Wind Load
Buildings obstruct wind flow. The energy of movement is converted to a pressure acting on the exposed surface of the building,, vertical, inclined and horizontal
14 of 15
Sensible Heat
the heat absorbed or given off by a substance that is NOT in the process of changing its physical state.
