# Shear Strain

on . Posted in Classical Mechanics

Shear strain, abbreviated as $$\gamma$$ (Greek symbol gamma), a dimensionless number, (measured in radians), is opposing forces acting parrallel to the cross-section of a body.

## Shear strain formula

$$\large{ \gamma = \frac{ \Delta y }{ l_i } }$$
Symbol English Metric
$$\large{ \gamma }$$  (Greek symbol gamma) = shear strain $$\large{deg}$$   $$\large{rad}$$
$$\large{ l_i }$$ = initial length $$\large{ in }$$ $$\large{ mm }$$
$$\large{ \Delta y }$$ = transverse displacement $$\large{ in }$$ $$\large{ mm }$$
