differece between proportional limit and yield point of a spring?
This relationship is known as Hooke's Law, which states, "The extension of a spring or wire is directly proportional to the force applied provided the limit of proportionality is not exceeded."
The physical significance of the spring constant is the characteristics of the spring. Hooke's law states that the force needed to compress or extend a spring by a specific distance is proportional to that distance.
For an ideal spring, yes. Real springs may deviate from this slightly.
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.

stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.

The proportional limit is the stress value at which the stress is no longer linear with strain. After that, the material will begin to yield and become non-linear, or plastic, and then it will fail at a higher value called the tensile strength. For most metals, the proportional limit is well below the tensile strength; for example annealed stainless steel has a proportional limit near 30 ksi and tensile strength of 80 ksi; aluminum has a proportional limit of 35 ksi and tensile strength of 42 ksi.
The displacement is proportional to the strain. This does not factor for creep and time.
Hooke's law states that the force needed to compress or extend a spring is directly proportional to the distance the spring is stretched or compressed, as long as the elastic limit of the material is not exceeded. In mathematical terms, this relationship can be expressed as F = kx, where F is the force, k is the spring constant, and x is the displacement from the equilibrium position.
The Law of elasticity states that the strain (deformation) of an elastic object is proportional to the stress applied to it. Since stresses and strains have multiple independent components, the 'proportionality factor' is represented by a linear map (a tensor) constituting a matrix of real numbers.
The fact that the displacement of the spring (the amount it stretches) is proportional to the force.
