Name: Date: 7. Deformation is referred to as: a. Whenever b. A rubber band C. Def d. r a force is applied to a body, it will tend to change the body\'s shape and size will undergo a very large deformation when stretched, whereas only ormation of a body can also occur when the temperature of the body is changed and they may be highly visible or practically unnoticeable. slight deformati ons of structural members occur when a building is occupied. thermal The deformation will not be uniform throughout the body, and so the change in geometry of any line segment within the body may vary substantially along its length. expansion or contraction of a roof caused by the weather. e. The vertical line is lengthened, the horizontal line is shortened, and the inclined line changes its length and rotates. All of the above f. What is the unit of strain or deformation? c. Microrn d. mm/mm or in./in. or m/m e. no unit A bar is subjected to an axial tensile stress.If the longitudinal strain in the bar is 0.44 times the lateral strain, what is the Poisson\'s ratio of the material? a. 0.44 b. 0.30 c. 0.28 d. None of above The rectangular beam \'A\' has length I, width b and depth d. Another beam \'B\' has the same length and depth but width is double that of\'A\'. The elastic strength (under same load/force of beam \'B\' will be as compared to beam A a. same b. one-half c. one-fourth d. one-eighth

Solution

7) option F is correct. All the statements refers to the deformation.

8) option D is correct.mm/mm, in/in and m/m are units for strain.

9) poisson ratio = lateral strain/longitudinal strain

= 1/0.44

=2.27

10) option B is correct. It will be one half of that of A.
