Question

The forces obtained at the joints and the members of the machines are very important. They are used for:

(a) The designing the size of the members, connections done in the frames and machines

(b) To determine the stress bearing capacity

(c) To know the strain bearing capacity

(d) They are not important

This question was posed to me in unit test.

The origin of the question is Frame and Machines in division Structural Analysis of Engineering Mechanics

Answer 1

Correct option is (a) The designing the size of the members, connections done in the frames and machines

For explanation I would say: The forces obtained at the joints and the members of the machines are very important. They are used for the designing the size of the members, connections done in the frames and machines. They are obtained by applying the simple equilibrium force equations on the system. Net forces are made to be zero, and the unknowns are determined.
