Question

For a statically indeterminate axially loaded member, Group of answer choices The total deflection between end A and end B of an axially loaded member must not be zero. The summation of the forces is not zero. The summation of the reaction forces is equal to the applied load. The applied load must exceed the total reaction forces. The compatibility condition cannot be satisfied, since it is indeterminate.

Answer 1

Answer: The summation of the reaction forces is equal to the applied load.

Explanation:

When solving an indeterminate structure, it is important for one to satisfy the force-displacement requirements, compatibility, and the equilibrium of the structure.

With regards to the above question, for a statically indeterminate axially loaded member, the summation of the reaction forces will be equal to applied load. Here, the summation of the reactive forces will then be zero. This is a condition that is necessary to solve the unknown reaction forces.
