What is mechanical engineering? - ANSWER Branch of engineering that focuses on the design,
production, analysis, working and improvement of technical objects with moving parts.
Which component connects parts of an object? - ANSWER Linking
What is the linking component? - ANSWER a solid part or fluid that performs a mechanical function (Ex:
a metal gear in a clock; the oil in a hydraulic piston)
What is linnking? - ANSWER the mechanical function performed by any component that connects
different parts of a technical object.
What is the difference between a direct and indirect link? - ANSWER A direct link does not need a linking
component, whereas an indirect link needs a linking component
What is difference between rigid and flexible link? - ANSWER when rigid, the linking components or
surfaces of the linked parts are rigid, and when flexible, the linking components or surfaces are able to
be deformed n(springs, rubber)
What is the difference between removable and non removable links? - ANSWER a removable link is
when linked partys can be separated without damaging the linked components or surfaces (nuts,
screws), non-removable links would damage the surface or linking components
What is the difference between a complete and partial link? - ANSWER A complete link would prevent
each part from moving independently of one another (scissors), a partial link is when at least one part
can move independently from the other
What are degrees of Freedom? - ANSWER are the set of independent movements that are possible for a
given part in a technical object (door - door stays still while hinges move)
, What does Tx mean? - ANSWER Translation from left to right or right to left
What does Ty mean? - ANSWER Translation from top to bottom or bottom to top
What does Tz mean? - ANSWER Translation from front to back or back to front
What does Rx mean? - ANSWER Rotation about the x axis
What does Ry mean? - ANSWER Rotation about the y axis
What does Rz mean? - ANSWER Rotation about the z axis?
What is the guiding component? - ANSWER a solid part or fluid that performs a mechanical function (Ex:
a door hinge; the track of a sliding window)
What is guiding? - ANSWER the mechanical function performed by any component that controls the
motion of one or more moving parts.
Translational guiding - ANSWER moves back and forth along a straight line
Examples: drawers, sliding window
Rotational guiding - ANSWER ensures an object rotates
Examples: scissors, bicycle wheel
Helicoidal guiding - ANSWER rotating a component ensures a translational motion (Ex: clamp, screw
press, faucet, jar cap)
What is adhesion? - ANSWER the phenomenon by which two surfaces tend to remain in contact with
each other without slipping
