What is the parameter that the two materials in a series compound member have in common when it is under load?
The parameter that the materials in a series compound member have in common when under load is the applied force or stress. This force is distributed through both materials in the member, but the specific amount each material experiences is determined by their individual properties.
What is the structural polysaccharide in bacteria?
Peptidoglycan is the structural polysaccharide found in bacterial cell walls. It provides rigidity and structural support to the cell, helping to maintain its shape and protect it from osmotic stress.
Max principle stress theory is valid for which material?
The maximum principal stress theory is generally applicable to materials that exhibit ductile behavior, such as many metals and alloys, where failure occurs when the maximum principal stress in a material exceeds its ultimate tensile strength. This theory is not suitable for brittle materials, as their failure is often governed by factors other than stress alone.
What are the causes of deformation?
Deformation of materials (called strain) is a response to forces acting on those materials (called stress).
What is elasticity in physical properties?
Elasticity in physical properties refers to the ability of a material to return to its original shape and size after being deformed. It is a measure of how much a material can stretch or compress under stress and then revert back to its original form once the stress is removed. Materials with high elasticity can undergo deformation without permanent damage, while materials with low elasticity may experience permanent deformation.
What elements are elastic?
Common elements that exhibit elastic properties include carbon, iron, copper, and aluminum. These elements have the ability to deform under stress, but return to their original shape once the stress is removed. Elasticity allows for various applications in materials such as springs, wires, and structural components.
What does structural stress mean?
Force per unit area is called Stress.
What material can break?
Materials like glass, ceramics, and ice are prone to breaking under stress or impact due to their brittle nature. Metals can also break under extreme stress or fatigue, particularly if they have weakened structural integrity.
What plays a critical role in the lone term effects of stress and it is the most common measure of stress?
The body's stress response system, specifically the release of cortisol, plays a critical role in the long-term effects of stress. Cortisol is the most common measure of stress as it reflects the body's ongoing efforts to cope with and manage stressors. High levels of cortisol over an extended period can have negative impacts on physical and mental health.
What are the different methods used for grading timber?
visual stress grading machine stress grading structural grading
What is cold crushing strength of refractory materials?
cold crushing strength of a refractory brick is gross compressive stress required to cause fracture. Maximum Structural load that a material can withstand without fracture
What is cold-crushing strength of refractory materials?
cold crushing strength of a refractory brick is gross compressive stress required to cause fracture. Maximum Structural load that a material can withstand without fracture
Is structural stress theory related to human ecological manifestations?
yes
What are photoelastic materials?
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.
What the fluid measure of viscosity?
Viscosity is the measure of friction between adjacent layers of materials.
What are all the types of stress?
structural, fatigue, flow. residual,and thermal
What is a structural system that defines space by transferring stress outward to its legs?
arch
