What is the relationship between stress and strain?
Stress is the load per unit area acting within a material. It can be thought of as the internal resistive response of a material to an externally applied pressure.Strain is the change in shape of an object in response to external pressure or internal stress. To complicate matters, strain causes the transmission of stress through an object (as in simple terms the strain causes an internal "movement" causing one part of the inside of an object to press against the material next to it generating stress in this region, this in turn can cause more strain and so on!).There are a number of differing types of strain, for example axial strain is defined as the change in length relative to the original length of an object (e.g. a steel wire being stretched). This change in shape is also called deformation. Volumetric strain occurs when an object is squashed or pulled on all sides leading to a change in volume.
What are shear stresses?
The forces are equal magnitude but opposite directions act tangent the surfaces of opposite ends of the object the shear stress as force "f" acting tangent to the surface,dived by the "area"{a} shear stress=f/a
Which comes first either stress or strain in an object?
When you have stress you also have strain - stress cannot exist without strain, so they come at the same time You can have strain without stress - like expanding something under temperature in a free state. If the state is not free, then you have stress occurring at the same time.
What is turbulent viscocity?
Turbulent viscosity is a value which is assumed to be equal in all directions. It is the same as Eddy Viscosity This is a measure of a fluid which is being deformed by stress. The fact that it is turbulent just means it is changing so the internal friction or viscosity is changing constantly and this is why it is called turbulent. the internal friction is the friction within the object hence the term internal however this friction derives from the force of the fluid acting on the object. E.G if air is your fluid surrounding the object and the object is experiencing a change in the velocity of the air it will be exposed to a different amount of stress and will therefore have a different value for internal friction.
Explain the difference between compressive stress and tensile stress?
Tensile Force -The force of pulling something apart. An example would be doing a tensile test on piece of steel to check the tensile strength. They put the piece of steel at a specified size in a machine that uses tensile force and pull apart the test sample. They measure the amount of force necessary to break apart the sample. All steel has a minimum standard of tensile strength required to be called this grade of steel. Compressive Force - The force of compressing an object. A common example is a cement sample compression test. Cements best quality is its compressive strength. This is why it is used as a foundation for buildings. Anyways, the test is placing a cement cylinder at a certain size in a compression machine. It basically squeezes the cement or compresses the cement to the point of rupture. Then they record the amount a compressive force it took to rupture the cement sample. It has to meet a minimum standard to be accepted or they reject the product made from this batch.
When stress squeezes an object is called?
When stress squeezes an object it is compression. When stress stretches an object it is called tension. The process by which the shape of a rock changes because of stress is called deformation.
When stress squeezes an object it's called?
When stress squeezes an object it is compression. When stress stretches an object it is called tension. The process by which the shape of a rock changes because of stress is called deformation.
When stress stretches an object it's called?
re formation
What is a force that stretches rock called?
Tensile force / stress.
What is the difference between torsion force and tension force?
if the force twists an obect, it is called torsion and if the force that stretches an object is called tension.
What is strain and stress?
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length

Tension
Which stress force pulls on the crust and stretches rock?
