10 Questions
What is stress proportional to in solids?
Force
In fluids, stress is proportional to what?
Strain rate
What is the normal component of the force acting on a surface per unit area called?
Normal stress
What happens when a constant shear force is applied to a solid?
It stops deforming at a fixed strain angle
What is the tangential component of a force acting on a surface per unit area called?
Shear stress
If a constant shear force is applied to a fluid, what will happen?
The fluid will continually deform, approaching a certain rate of strain.
What is the relationship between stress and strain in solids?
Stress is proportional to strain.
How is stress defined?
Stress is defined as the force per unit area.
If a constant shear force is applied to a solid, what will happen?
The solid will stop deforming after reaching a fixed strain angle.
What is the relationship between stress and strain rate in fluids?
Stress is proportional to strain rate.
This quiz covers the relationship between stress and strain in solids and fluids. Topics include the proportional nature of stress to strain or strain rate, the behavior of solids and fluids under shear force, and the definition of stress and normal stress.
