WebWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx. Where F F is the force, x x is the length of extension/compression and k k is a constant of proportionality known as ... WebSep 20, 2024 · What is elastic limit in physics class 11? Elastic limit is the maximum stress a material can withstand before the permanent deformation. It is the material’s highest limit before the material’s plastic deformation can occur. Once the stress or force is removed from the material, the material comes back to its original shape.
WebElastic limit is the greatest pressure that we can apply to a material without causing plastic (lasting) deformation. For some materials elasticity limit is the same or almost equivalent to the proportional limit. For different … WebJun 28, 2024 · 11.

WebElastic limit is the limit up to which the object will undergo elastic deformation. Stress is the force acting on a unit area. The changes in dimension when divided by the original dimension give the measurement of Strain. SI unit of stress is Newton per meter square (N/m²) or pascal (Pa). There is no unit for strain.
