For materials that are brittle rather than ductile. For ductile :max shear stress theory would be more suitable
The correspondence principle has applications to macroscopic events in the everyday macro-world. This principle is a general rule not only good for science but for all good theory - even in areas as far removed from science as government, religion, and ethics. If a new theory is valid, it must account for the verified results of the old theory.
Yes. As far as I am aware, no exceptions are known.
Yes, a theory should be supported by evidence in order to be considered valid and credible. Evidence helps to substantiate the claims and predictions made by a theory, allowing for testing, verification, and refinement of the theory as needed.
More than 150 years the theory of Proust was considered generally valid; but now the rule of definite proportions is not generally applicable. The Proust law can be considered as a particular case of the Berthollet principle.
Yes, ecological approaches have a valid place in contemporary criminological thinking. They emphasize the importance of understanding how social and physical environments contribute to criminal behavior, and how interventions can be targeted at these different levels to prevent crime. Ecological theories such as social disorganization theory and routine activities theory continue to be influential in explaining crime patterns.
It is valid
Yes, in theory. But it is only valid up to a certain point of stress, after which the molecular bonds starts to break down. In reality, some materials are so difficult to stretch (so brittle) that it is almost impossible to apply Hooke's law to them. (Our school teacher use to say: dunk a biscuit into tea and then try to stretch it)
it is not valid for hydrogen
There is confusion over this because "law" and "theory" mean very different things in every day life compared to science. A "law" is just an outdated term for "theory." Theories are explanations of a phenomenon that have undergone rigorous experiments by scientists. A law is no more scientifically valid than a theory in science. A principle is usually more specific than a theory. For instance, you have the Theory of Quantum Mechanics and within that, you have Pauli's exclusion principle.

why caveat emptor principal is not fully valid in the present scenario
when it is consistent with observation
when the principle die the irrevocable power of attorney is valid or invalid
Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.
The principle of falsifiability states that any theory or hypothesis being tested must be stated in a way that allows the possibility for disproving, rejecting or showing as inaccurate that theory or hypothesis through scientific methods, techniques and procedures. If you state a hypothesis that renders it immune to any attempts for rejecting it via scientific methods, then you have violated the falsifiability principle and such hypotheses or theories are scientifically non-viable. You must make predictions that allow your hypothesis to be shown as incorrect.
