What is strain to failure?
strain-to-failure
How do you calibrate strain gauges?
The strain gage indicates strain, and the stress is from Hooke's law; stress = modulus times strain so you need to know the modulus of elasticity
What happens to strain when stress is increased in a material?
It also increases. It increases linearly with stress in the elastic range, then increass more rapidly once the material is plastic ( yielded).
Difference between unbonded strain gauge and bonded strain gauge?
The essential difference is that the bonded strain gauges are bonded on to the specimen whose strain is being measured whereas the unbonded strain gauges are not bonded on to the specimen. As the bonded strain gauges are well bonded on to the specimen, the entire strain being experienced by the specimen is transferred to the strain gauge. However, the bonded strain gauges are affected by temperature changes and also due to transverse strains.For transverse strains and ambient temperature compensations, suitable circuits for compensation can be used using Wheatstone's bridge. The unbonded strain gauges cannot transfer the strain of the specimen to the strain gauge and hence it is used mainly for displacement, or pressure or force transducers. It is least affected by transverse strain and temperature compensation of unbonded gauges cis automatically eliminated using Wheatstone's bridge.
What is liquid metal strain gauge?
mercury in tube strain gage.
What states that within the limits of elasticity the stress is proportional to strain?
Young modulus
What is strain gauge?
* a device that responds to mechanical strain. with a small change in resistance. ... * device for determining the amount of strain (change in dimensions) when a stress is applied
Why did the earthquake take place?
Because the strain built up in the moving subduction zone rocks just off the coast of Japan reached a point that exceeded the strength of those rocks, resulting in the rocks fracturing and sliding very rapidly to relieve the strain.
What sort of structure does the spectrum of a pulse train have?
A pulse strain has a structure called a frequency comb. This is a spectrum that has a series of discrete and equally spaced elements.
What are the Stress-strain characteristics of organic materials?
it depends on its chemical structure, enviromental factors and its bonding forces.
What are the three branches of social structure theory?
social disorganization, strain theory, and cultural deviance theory
What kind of injury happens if a muscle is stretched too far?
boo boo strain
What happens to strain as stress increases?
it also increases in the same proportion as stress. Stress equals strain times a constant, where the constant is Young's modulus. This is Hooke's Law
What happens if you consume too much or too little protein?
too much protein can cause strain on the kidneys too much protein can cause strain on the kidneys
What happens whe ligaments or joints are pulled beyond their normal range?
A sprain - The medial collateral ligament is on the inner side of your knee and is tight when your leg is straight. It's a strong ligament but can be sprained or completely ruptured (torn) if you twist your straightened leg at the same time as being knocked sideways, for example, when being tackled in rugby.
What is the difference between steric and torsional strain?
I think torsional strain happens only when two groups are eclipsed in relation to their positions to each other. This strain can be relieved by rotation about the carbon carbon bond. But steric strain can happen all the time. (when two groups are eclipsed, gauge or staggered in relation to each other.)
What happens when you get a hamstring injury?
It depends on the severity of the injury and the location. A tear in the muscle or tendon is called a strain.
