11 Questions
What is the formula for stress?
$\frac{\text{Applied Force}}{\text{Area}}$
What is the unit of stress?
N/m$^2$
What is the dimensional formula of stress?
$[ML^{-1}T^{-2}]$
What is the type of stress when there is an increase in the length of the object under the effect of applied force?
Tensile stress
What is the type of stress produced when a deforming force acts tangentially to the surface of a body?
Tangential or shearing stress
Define stress and provide its formula.
Stress is the internal restoring force setup per unit area of cross-section of the deformed body. The formula for stress is $\text{Stress} = \frac{\text{Applied Force}}{\text{Area}}$.
What are the different types of stress?
The different types of stress are: 1. Longitudinal stress, further categorized into (a) Tensile stress and (b) Compressional stress. 2. Tangential or shearing stress. 3. Normal stress.
What is the definition of longitudinal stress?
Longitudinal stress occurs when the deforming force is applied normal to the area of cross-section of the body.
What is the definition of normal stress?
Normal stress occurs when a body is subjected to a uniform force from all sides, and is also known as hydrostatic stress.
What is strain?
Strain is the fractional change in configuration that a body undergoes when a deforming force acts on it, causing a change in its shape and size.
change in dimension is known as
deformation
