MEGR EXAM 1 PART 1 QUESTIONS
AND ANSWERS
What is the best description for the subject of mechanics? - Correct Answers -It is the
physical science that deals with the effects of forces on objects.
The applications of the principles of mechanics. - Correct Answers -Stability, strength
and stiffness of structures and machines.
According to the textbook, which subject is the oldest of the physical sciences? -
Correct Answers -Mechanics.
Who formulated most of the principles of statics according to the textbook? - Correct
Answers -Stevinus.
When the angle x is small, we can use the approximations of sinx=x, or tanx=x. In these
approximations, the terms 'x' on the left are in degrees and the terms 'x' on the right are
in radians. - Correct Answers -True.
We may use symbolic solutions or numerical solutions when doing a static problem.
Which type of solutions has more advantages? - Correct Answers -Symbolic solutions.
Who wrote the earliest works in mechanics, according to the text book? - Correct
Answers -Archimedes.
When the coordination system is rotated, the components of a vector will be changed.
Therefore, the vector itself will be changed. - Correct Answers -False.
When the complete specification of the action of a force must include its magnitude,
direction and point of application, we must treat the force as a: - Correct Answers -A
fixed vector.
Which one is correct?
Forces external to a body can only be applied forces.
Forces external to a body can only be reactive forces.
Forces externa to a body can be either applied forces or reactive forces. - Correct
Answers -Forces externa to a body can be either applied forces or reactive forces.
