Describe in Detail
Starting with Newton’s second law of motion, establish D’ Alembert’s principle and discuss its significance? (Paper1) (Section –A)
Explanation

Let consider a system described by generalized coordinates . And this system undergoes a certain displacement in configuration space. If for this displacement it does not take any time and it is consistent with the… (416 more words) …
