  1. Answer the following questions:

    1. What is deformation? Give your own example.

    2. What is stress?

    3. When the stress is expressed in pounds per square inch?

    4. In what components the plane may be resolved?

    5. What is compression?

    6. What is shear?

    7. What do you know about the effect of a normal stress?

  1. Translate the following words and word combinations into Ukrainian:

external force, elastic body, deformation, change of shape, tensile load, cross section area, compressive load, solid body, internal resistance, intensity of stress, square inch, finite, infinitesimal, cross section, wire, direct stress, tangential component, to produce extension, lengthening or shortening of the fibers, dimension, angular deformation, pound, body.

  1. Match the first part of the sentence (1-7) with the second part (a-g).

    2. All solid bodies offer more or less resistance to the .….

    3. In general the stress is not the same at all points .….

    4. The perpendicular, or normal, component is called .....

    5. The tangential component, or that lying in .....

    6. The internal resistance, when expressed in ......

    7. The letter p will always be used to denote normal, or direct stress …..

      1. ….. of a body, but varies from point to point.

      2. ….. the plane of the cross section, is called shear.

      3. ….. deformation, or change of shape, produced by external force.

      4. ….. definite units, is called stress.

      5. ….. and q to denote tangential stress, or shear.

      6. ….. is to produce deformation, or change of shape.

      7. ….. direct stress and is either tension or compression.
