**Shear**Force : A good

**example of shear**force is seen with a simple scissors. The two handles put force in different directions on the pin that holds the two parts together. The force applied to the pin is called

**shear**force. COMPRESSION.

Consequently, what is the definition of shear stress?

**Shear stress**, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed

**stress**. The resultant

**shear**is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.

What is the definition of a shear force?

**Shearing forces**are unaligned

**forces**pushing one part of a body in one specific direction, and another part of the body in the opposite direction. William A. Nash defines

**shear force**in terms of planes: "If a plane

**is**passed through a body, a

**force**acting along this plane

**is**called a

**shear force**or

**shearing force**."

What are the units of shear strain?

Measures of

**strain**are often expressed in parts per million or microstrains. The true**shear strain**is defined as the change in the angle (in radians) between two material line elements initially perpendicular to each other in the undeformed or initial configuration.
