50% of total deformation non-elastic deformation elastic deformation last 25% of deformation
reciprocal of normal strain within elastic limit normal strain at yield point normal strain within elastic limit normal strain within proportional limit
ultimate strength ductility strength yield stress
one end hinge and other on rollers one end fixed and the other on rollers both ends on rollers one end fixed and the other free
the S.F. is uniform the S.F. is maximum the S.F. is zero none of these
flexural rigidity torsional rigidity second moment of area none of these
the resistance to the force acting large deformability as in case of rubber the property by which a body returns to its original shape after removal of the load the ratio of stress to strain
that body which recovers its original shape completely after removal of force a body of such a material with a lot of extensibility a body whose cross-sectional dimensions are very small a body made of rubber only
