Mechanical Engineering Flashcards
What is a Mechanical function?
The role played by a specific part of a technical object, there a four basic mechanical functions: Link, Guiding, Lubrication, & Sealing.
What is Linking?
To join two parts together.
What is Guiding?
To guide another part in it’s motion.
What is Lubrication?
To limit friction between two parts.
What is Sealing?
To stop air and water from entering.
What is an example of a link?
- Glue
- Tape
- Screw
- Bolt
- Staples
What is an example of guiding?
- Rails
- Axle
What is an example of lubrication?
- Skis
- Snowboard
- Surfboard
- Oil
What is an example of sealing?
- O-rings
- Bottle cap
What are the three types of guiding? (Motion)
- Translational
- Rotational
- Helical
What is a Translational motion?
Motion in which all points of a moving body move uniformly in the same direction, side-to-side or up and down.
What is a Rotational motion?
Motion of an object around a circular path, in a fixed orbit.
What is a Helical motion?
Motion of an object in which goes side-to-side or up and down, while rotating around a circular path.
What is a Motion Transmission?
The mechanical function of relaying a motion from one part to another without altering the nature of the motion.
What is a Motion Transmission System?
A set of components that perform the function of a transmitting motion.
What is the Driver component?
The part that receives the force required to activate the system.
What is the Driven component?
The part that receives the motion and transfers it to another part.
What is the Intermediate component?
The part that is located in between the Driver & Driven components.
