Launch the simulation, then answer the question Part A Equations of Equilibrium In drawing a free-body diagram for a two-dimensional body, which of the following is correct The sense of a force or couple moment having an O unknown magnitude but known line of action can be assumed The sense of a force or couple moment having an correctly along its Ine of action. O unknown magnitude must always be specified o t is always necessary to employ two force and one moment equilibrium equations equilibrium problem with one force and two moment equilibrium equations Submit Incorrect; One attempt remaining: Try Again Provide Feedback Next >

Solution

Option B is correct. A force or couple must be specified along it\'s line of action even then it\'s magnitude is not known.

It is not necessary of two force and one moment equilibrium equations. It is possible with one force and two equilibrium equations.
