Topic: Engineering Mechanics
A moving fluid mass may be brought to a static equilibrium position by applying an imaginary inertia force of the same magnitude as that of the accelerating force but in the opposite direction. This is called
- A. Pascal's law
- B. Archimedes principle
- C. D-Alembert's principle
- D. None of the above
Answer: C. D-Alembert's principle
Explanation: D-Alembert's Principle states that a body is in dynamic equilibrium under the action of an effective force and an imaginary inertia force. The purpose of this principle is to convert a complex dynamic problem into an equivalent static problem. The inertia force always acts opposite to the direction of acceleration.
