Is it the stress that produces strain or strain produces stress?

A Force applied to an object will cause a displacement. Strain is effectively a measure of this displacement (change in length divided by original length). Stress is the Force applied divided by the area it is applied to. (eg. pounds per square inch) So, to answer the question, it is the applied Force that produces both stress and strain. Stress and strain are linked together by various material properties such as Poisson's ratio and Young's Modulus.

Can stress exists without strain and vice versa. eg a heated bar held rigidly at both ends has no strain but there is stress?
Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
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

What is hysteresis loop in stress and strain?
the leading or lagging between the stress and strain is called hysteresis loop

What are two definitions for stress?
In Phonetics, to pronounce a word or syllable with prominent loudness. To stress a word in a sentence to emphasise its importance. In Mechanics, the force of something that produces deformation or a strain

Is the ratio of stress-strain in the region below the proportional limit on the stress-strain curve?
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
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 is Secant Modulus?
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
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.

Why stres is directly proportional to strain?
Yeah, according to the Hooke's law of elasticity,the stress is proportional to the strain within elastic limit that is Stress ∝ Strain or Stress/Strain = constant. [The constant of proportionality is called as "modulus of elasticity" or "coefficient of elasticity".]
