How is the analysis of dynamic systems made simpler by D'Alembert's Principle?

62. How is the analysis of dynamic systems made simpler by D'Alembert's Principle?

1. By ignoring inertial effects in motion analysis
2. By converting dynamic problems into static equilibrium problems
3. By introducing additional variables to equations of motion
4. By eliminating the need for Newton's laws of motion

Answer

The correct answer is: B) By converting dynamic problems into static equilibrium problems

Explanation

By using D'Alembert's Principle, engineers can simplify the analyses by converting dynamic challenges into equivalent static equilibrium problems. To balance out the dynamics and facilitate the use of statics concepts, it introduces inertial forces.
