Wherever some external system of forces acts on a body, it undergoes some deformation. As the body under goes some deformation, it sets up some resistance to the deformations. This resistance per unit area to deformation, is called
Which of the following is a proper sequence ?
The deformation of a bar under its own weight is __________ the deformation, if the same body is subjected to a direct load equal to weight of the body.
The elongation of a conical bar under its own weight is ......that of prismatic bar of the same length.
