Chapter 13: Mechanical Engineering Flashcards
What is a link?
Any part such as a nail or staple, or any fluid such as glue, that holds together a technical object performs a
mechanical function
What is a direct link?
Two parts hold together without a linking component
What is a indirect link?
Two things that require a link to be together
What is a rigid link?
A link where its compnets are rigid
What is a flexible link?
a linking component that can be deformed
what is a remouvable link?
Remouving said link would not damgage the stucture
what is a non remuvable link?
removing the link would damage the componets being linked
what is a complete link?
Link that pervents the linked parts from moving independently (one part cannot move without the other part moving)
What is a partial link?
Link allows parts to move independently from one another
Name the two degrees of freedom?
Translational and Rotational
What is Tx, Ty, and Tz.
Tx: left to right/right to left
Ty: top to bottem/ bottem to top
Tz: front to back/back to front
what is Rx, Ry, Rz?
Rx: rotation around the x axis.
Ry: rotation around the y axis.
Rz: rotation around the z axis.
What are the three types of guiding components?
Type 1: Translational Guid
Type 2: Rotational guide
TYpe 3: Hellicle guide
What is a translational guide?
Straight line motion
What is a rotational guide?
Rotational motion (weel)
What is a helical guide?
guide moves in a straight line hwile turning
What is a motional transmission system?
System that transfers the SAME type of motion from one part to another
What is a motion tranformation system?
System that transfers a different type of motion from one part to another.
What is the driver componet?
The first compoent to recvie the force
What is the driven?
Controled by the driver and recives the motion
What is the intermediate component?
Link between driver and driven
Is ther an increse or decrease in speed if the gear is larger to smaller?
INCREASE
Is there an increse or decrease in speed if the gear is smaller to larger?
Decrese
What happends if the gears r the same?
No change in speed
