1. A vibratory system where proportionality can be established between the motion and the force produced by the element, what is the resulting vibration. a. Free Vibration b. Force Vibration c. Non-Linear Vibration d. Linear Vibration 2. A block with a spring attached and the other end on a wall exhibits an oscillating motion. Due to the continuous rubbing of the floor and the block surface, friction is produced. The presence of friction can be considered as: a. Mass Element b. Spring Element c. Friction is not part of the vibrating system d. Damping element 3. The number of degrees of freedom of the system is (a. same, b. more, c. less, d. unrelated) as the number of the independent spatial coordinates that can describe the system.
