Slope of stress-strain curve in elastic deformation region is a. plastic modulus b. poisson's ratio c. elastic modulus d. none the these a) all of these

c) Elastic Modulus

Explanation

As we know that when deformation is under elastic limit then stress applied to the given material is proportional to the strain developed in it

So here we can say that since they both are directly proportional to each other so the proportionality constant here is known as Modulus of elasticity.

So we can say it is given as

so now if we draw a graph between between stress and strain then it must be a straight line and the the slope of this straight line is given as

So here correct answer will be

c) Elastic Modulus

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
