What is the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
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
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 the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What is the relationship between engineering strain and percent elongation?
strain is percent elongation/100; for example a strain of 0.02 is 2% elongation. Often we refer to elongation at failure; for example if a material fails at 10% elongation its strain is 0.10
What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
What materials are weak?
Any material that is prone to failure dependent on the stress/strain before reaching a mean life cycle.
Is mild steel ductile at room teperature?
Yes, it is - it has a yield point and can strain quite a bit 20% or so before failure
Does a kidney strain have long term affects?
Clearly dietary protein effects GFR [50], with both acute and chronic .... protein intake would have a longer time to renal failure and suggested that a lower ... to the kidney and represent the physiological "strain".
What has the author E Alf written?
E. Alf has written: 'Forming of cracks and failure of welding joints depending on temperature, media influence and strain'
Stress strain curve for brittle material?
Brittle materials such as ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same, therefore the stress-strain curve would consist of only the elastic region, followed by a failure of the material.
Obstruction of circulation through the lungs can put a strain on the right ventricle which must work to pump blood against this increased resistance and can lead to failure of that chamber?
cor pulmonale
Why do some doctors recommend low sodium diets?
People with kidney failure are advised to eat low salt diets. A low sodium diet is recommended to those in kidney failure to lessen the strain on the kidneys.
The s strain and the r strain of S pneumoniae are different in that?
The S strain produces a capsule but the R strain does not
Is there more than one cause of strain?
Yes, for causes. Disjunction of expectations and achievements, Failure to achieve positively valued goals, Removal of positively valued stimuli, Presentation of negative stimuli.
