Multiple choice questions (mcq) on force and friction

In this mechanical engineering lecture today we learned about engineering mechanics subjects Multiple choice questions (mcq) on force and friction (objectives questions and answers)

Guys this friction mcq is important for mechanical engineering student for all competitive exam.

Know without wasting time let's begin to start Friction mcqs ( objectives) questions with answers
