Load is acting parallel to member axis. Stress is uniform for homogeneous sections. If due to tension - tends to elongate the body. If due to compression - Tends to shorten the body
- Axial Deformation
- Bending
- Shear
- Torsion
- Bearing
Correct Answer

A. Axial Deformation

Explanation

Axial deformation refers to the change in length of a member along its axis due to the application of an axial load. When a member is subjected to tension, it tends to elongate, causing axial deformation. Similarly, when a member is subjected to compression, it tends to shorten, resulting in axial deformation. This is because the load is acting parallel to the member axis, and the stress is uniform for homogeneous sections. Therefore, the correct answer is axial deformation.

Correct Answer

A. Determinate Structure

Explanation

A determinate structure is a type of structure in which the reaction components and internal stresses can be completely determined using the equations of static equilibrium. This means that all the forces and moments acting on the structure can be calculated and the structure can be analyzed using the principles of statics. In a determinate structure, the number of unknowns is equal to the number of equations available, allowing for a unique solution to be obtained. This is in contrast to an indeterminate structure, where the number of unknowns exceeds the number of equations, resulting in multiple possible solutions.
