1. The document contains a quiz with three parts - identification questions, discussion questions, and mechanism problems. 2. The identification questions cover basic mechanism terms like machine, degree of freedom, kinematic diagram. 3. The discussion questions ask about the differences between machines and mechanisms, how degree of freedom is determined, and how a slider-crank mechanism relates to a four bar mechanism. 4. The mechanism problems involve describing a mechanism's function, calculating its degree of freedom, sketching its kinematic diagram, and graphically solving for displacement.

1. NAME: ______________________________________________________________________ Section: __________
Quiz 1:
Part 1: Identification. Identify the following. (1 pt each).
1. ____________ is a device consisting of fixed and moving parts that converts mechanical energy and
transmits it in a useful form.
2. When the two elements have surface contact while in motion, the pair is known as ____________.
3. When the two elements of a pair are held together mechanically in such a manner that only the
required type of relative motion occurs, then the pair is called a/an ____________.
4. Degree of freedom of a screw pair is ____________.
5. A/An ____________ is defined as an assembly of links in which relative motion of links is possible and
the motion of each relative to the other is definite.
6. ____________ deals with the relative motion between the parts, neglecting the forces which act on
them.
7. ____________is when one link has a turning or revolving motion relative to the other.
8. When the degree of freedom is zero, then it is known to be a/an ____________.
