What is an automata?
A programmable robot
A hand-powered mechanical device that performs a repeating motion
A steam-powered computer
A hydraulic-powered transport system
Which of the following is NOT a typical part of an automata?
Crank handle
Rod guide
Fuel injector
Axle or drive shaft
What does the pusher rod do in an automata?
Controls the speed of rotation
Transfers motion from the drive shaft to moving parts
Secures the cam in place
Allows manual movement of parts
What is the function of the rod foot (follower)?
Converts energy into electricity
Moves parts in a circular path
Follows the cam and causes vertical movement
Locks parts in place
What does the rod guide do in an automata?
Connects the crank to the frame
Keeps the rod moving smoothly and in a straight path
Increases speed
Stops movement
What is the purpose of the stopper?
Adds friction to slow the motion
Stops the crank from rotating
Prevents the rod from falling out
Prevents the drive shaft from failing out and helps align the cam with the follower
What does the axle or drive shaft do in an automata?
It powers an electric motor
It connects the automata to an engine
It transmits rotary motion to the cam
It prevents the automata from moving
What does the handle do in an automata?
Changes the automata's speed
Allows manual input of rotary motion
Secures the base
Controls sound output
What correctly describes a pivot?
A gear that rotates other parts
A fixed point around which something moves
A tool for cutting wood
A stopper in the axle
What is reciprocating motion?
Side-to-side swinging motion
Circular spinning motion
Up-and-down or back-and-forth linear motion
Diagonal sliding motion
What is oscillating motion?
A continuous forward push
A motion in one direction only
A repetitive swinging from a central point
A twisting motion around a corner
Which cam stays stationary for a while before a fast rise and fall?
Elliptical cam
Snail cam
Pear cam
Hex cam
Which cam has multiple rises and falls in a full rotation and never stops moving?
Hex cam
Snail cam
Pear cam
Elliptical cam
This cam produces two quick rises and falls in a full rotation. What is it?
Pear cam
Elliptical cam
Snail cam
Hex cam
What type of motion is shown when a crank is turned in a circle?
Linear motion
Reciprocating motion
Oscillating motion
Rotary motion
The repetitive up-and-down motion of a piston is an example of:
Linear motion
Oscillating motion
Rotary motion
Reciprocating motion
The flapping of a bird's wings is an example of:
Linear motion
Rotary motion
Oscillating motion
Reciprocating motion
Which design change would allow an automata to have oscillating motion instead of reciprocating?
Add a motor
Use two offset circle cams with a pivot system
Replace the crank with a spring
Switch the axle for a larger one
Why is precise rod guide placement important in an automata?
It decorates the automata
It reduces material cost
It ensures smooth vertical motion
It makes assembly faster
