For quicker problem solving in mechanics one should know 1st year engineering level concepts like DAlemberts principle,Work Energy principle,virtual work priniple, concept of centreof mass etc.

Plz suggest some books which have this approach.

Also suggest some 1st year engineering mechanics books which can be solved by a +2 student.

Dear Sougat,

For that purpose ML Khannna is a good book.
