The study of external forces applied on a body inducing any motion

Does not deform under load

Amount of force

Orientation of the path where the force will be imposed

Usually said to be a physical quantity that only has a magnitude and no other characteristics

A quantity that has both magnitude and direction

Loads that are concentrated imposed at a point on a free body diagram

Series of concentrated loads with uniform magnitude

Series of concentrated loads with varying magnitude

A set of forces having the same direction but do not converge at a common point

A set of forces that lie along the same straight line

A set of forces acting on a single plane

A set of forces having all its directions converge at a common point

Representative force of the cumulative effects of forces

Part of the resultant force resolved at the direction of the coordinate axes

Reactive force developed by a body on which a force or system of force acts

Reactive force developed by a body on which a force or system of force acts

Forces done along the longitudinal axis or the length of the material

Stress that develops to resist axial force

Forces done perpendicular the longitudinal axis or the length of the material

Stress that develops to resist shear force

Type of axial load which is an act of shortening or state of pushing together

Type of axial load which is an act of stretching or state of pulling apart

Type of eccentric force where force producing both tension and compression on to the cross-section of the body

Type of eccentric force where there is a twisting effect on to the cross section

The tendency of a force to cause rotation about a point

Shortest distance of a force from the point or axis

A state in which the resultant of the force system that acts on a body vanishes

Means that both a resultant force and the resultant couple is zero

When dealing with moments, if a force tends to cause a clockwise rotation, the moment is?

When dealing with moments, if a force tends to cause a counterclockwise rotation, the moment is?

The internal resistance to an external force

When the material is subjected to a change in temperature, it expands if heated or contracts/shrink if cooled

The deformation of a material caused by external forces

The ratio of the total change in length of a material to its original length

Lines depicting the direction but not the magnitude of the principal stress of the beam

Also called as extensometer

An instrument to measure a minute deformation

Within the proportional limit, the stress is directly proportional to strain or the constant of proportionality k is called the Modulus of Elasticity E or Young's Modulus and is equal to the slope of the stress-strain diagram from O to P.

Within the proportional limit, the stress is directly proportional to strain or the constant of proportionality k is called the Modulus of Elasticity E or Young's Modulus and is equal to the slope of the stress-strain diagram from O to P.

The stress-strain curve is a straight line. This linear relation between elongation and the axial force causing was first noticed by who?

Also known as Hooke's Law

The limit beyond which the material will go back to its original shape when the load is removed, or it is the maximum stress that may developed such that there is no permanent or residual deformation when the load is entirely removed

The region in stress-strain diagram from O to P is called what?

The region in stress-strain diagram from P to R is called what?

The work done on a unit volume of material as the force is gradually increased from O to P, in Nm/m³

This may be calculated as the area under the stress-strain curve from the origin O to up to the elastic limit E

The resilience of the material is its ability to absorb energy without creating a permanent distortion

The work done on a unit volume of material as the force is gradually increased from O to R, in Nm/m³

This may be calculated as the area under the entire stress-strain curve from O to R.

The toughness of a material is its ability to absorb energy without causing it to break
