Constraints & Deformations
Crushing a soda can is an example of this constraint.
What is compression?
The ability to resist shocks without breaking.
What is resilience?
A link where the 2 parts are hard.
What is a rigid link?
True/False: A gear train is a reversible system.
You can reduce the speed of a gear system by making the following change.
Reducing the size/number of teeth of the driver gear.
OR
Increasing the size/number of teeth of the driven gear.
The material deformation where you break the material.
What is a "fracture"?
The ability to return to their original shapes after undergoing a constraint.
What is elasticity?
The 3 types of guiding.
What are translational, rotational, and helical guiding?
A cam and follower is an example of this type of system.
What is a motion transformation system?
OR
What is a non-reversible system?
This material is low in thermal and electrical conductivity and can be very fragile.
What are ceramics?
A constraint typically associated with bending.
What is deflection?
Ability to resist indentation or scratches.
What is hardness?
A characteristic of a link describing that 2 parts are held together by a (third) linking part.
What is an indirect link?
A bicycle is an example of this type of motion transmission system.
What is a chain and sprocket system?
The driver gear has 20 teeth and the driven has 10 teeth. What is the speed ratio?
2
A constraint associated with twisting.
What is torsion?
Ability to retain their shapes when subjected to various constraints.
What is stiffness?
An axle in a bicycle is an example of this type of guiding.
What is rotational guiding?
A rack and pinion can transform rotational motion into this type of motion.
What is translational motion?
The main cause of degradation of this material is oxidation (rusting) which causes corrosion.
What are metals and alloys?
A material deformation where you cause a permanent change to the shape of a material.
What is a plastic deformation?
Ability to be flattened or bent without breaking.
What is malleability?
A link where the 2 parts move together.
What is a complete link?
A car jack is an example of this type of motion transformation system.
What is "screw gear type 1"?
Wood and modified wood have low _____ and ______ conductivity.
What is thermal and electrical?
