Shortcuts used while solving elasticity numericals

Some important tips to remember for ELASTICITY

• Glass is more elastic than rubber
• Modulus of rigidity for liquid is ZERO
• Stress is a tensor quantity.
• Young's Modulus for a perfectly rigid object is infinity
• Stress is always followed by strain
• The measurements of the deformation in any object is nothing but strain
• Young's modulus is the property only associated with the solids
• Bulk modulus is connected with solid, liquid & gases
• The total amount of workdone in stretching a wire is area under load extension curve.
• Breaking load = Breaking stress x area of cross section
• Breaking force depends on the area of cross section and breaking stress for a wire is called as tensile strength.

Also remember,

• The force that produces deformation in objects is called as deforming force.
