True or False. Draw if the statement is True. Otherwise, draw if the statement is False. 1. Free-body diagram is a sketch of the body showing all forces that act on it. 2. Statics deals with bodies that are either at rest or moving in constant acceleration. 3. Third Law of Motion states that for every action, there is an equal but oppositely directed reaction. 4. A scalar is a quantity that has magnitude and direction. 5. Principle of Transmissibility states that the motion of a rigid body remains unchanged if the force acting on it is replaced by another force of the same magnitude and same direction, but acting on a different point, provided that it passes through the same line of action as of the original given force. 6. Varignon's Theorem states that the moment of a force is equivalent to the product of the moments of its components. 7. A couple will have the same effect regardless of its position given that it is lying along the same plane. 8 A force will have the same effect regardless of its position given that it hasthe same magnitude and direction, and that it is lying along the samie plane. 9. 47 lb-in is equivalent to 4.31 N-m. 10.2x 10 N/mm- is equivalent to 200 GPa.
