I would Ike to be more explanatory on this.
when force is applied on object(e.g. a piece )certain area or ideally speaking whole area (c/s) tries to elongate or compress.but due to elastic property of material,piece on which force is acted,tries to regain its past shape or stage so one resistant force is developed.This force is called stress.and stress intensity is given by:
mechanical stress is force divided by area
σ=F/A
if unit of F is Newton and area in Sq. m
then mech. stress is in Pascal

im doing my first year in mechanical engineering technology, and the hardest course so far are dynamics, statics and stress analysis.

main effect of mechanical stress
Mechanical stress is due to the resistance offered by various materials against physical distortion or damage. Thermal stress is caused due to the expansion of materials due to the variations in temperature with respect to reference value.
Normal stress and shear stress are two types of stresses that act on a material under mechanical loading. Normal stress is a force applied perpendicular to the surface of the material, while shear stress is a force applied parallel to the surface. The relationship between normal stress and shear stress depends on the material's properties and the direction of the applied forces. In general, normal stress and shear stress can interact and affect each other, leading to complex mechanical behaviors in the material.
You might be thinking of a stress fracture; a fracture of a bone caused by repeated (rather than sudden) mechanical stress.

The relationship between stress and strain determines how materials respond to mechanical forces. Stress is the force applied to a material, while strain is the resulting deformation. When a material is subjected to stress, it deforms or changes shape, which is known as strain. The behavior of materials under mechanical loading is influenced by how they respond to stress and strain. Materials can exhibit different properties such as elasticity, plasticity, and brittleness based on their stress-strain relationship.

Photoelastic materials are transparent materials that change their optical properties when subjected to mechanical stress. When stress is applied, these materials exhibit a birefringence effect, which causes them to change colors or patterns under polarized light. They are commonly used in stress analysis and to visualize stress distributions in mechanical components.
The relationship between stress and strain in materials under mechanical deformation is described by Hooke's Law, which states that stress is directly proportional to strain. This means that as a material is subjected to a force (stress), it will deform (strain) in a predictable and linear manner. The relationship between stress and strain helps engineers and scientists understand how materials behave under different conditions and can be used to predict their mechanical properties.
They are all mechanical stresses. Push is a compressive stress. Pull is a tensile stress and Twist is a type of shear stress.
Aside from mechanical stress, other types of stress that can cause piezoluminescence in p lunula cells include electrical stress, thermal stress, and chemical stress. These stressors can trigger the release of energy, resulting in light emission from the crystals in the p lunula cells.
