What is the mechanical advantage (IMA) of a single fixed pulley?
0
1
2
Depends on the rope length
In a block and tackle system, what increases the mechanical advantage?
Shorter rope
More pulleys
Heavier load
Longer lever
What does AMA stand for?
Actual Mechanical Advantage
Average Motion Analysis
Applied Machine Action
Axle Motion Adjustment
How do you calculate IMA for a pulley system?
Divide effort force by resistance force
Count the number of strands supporting the load
Multiply pulley diameter by rope length
Subtract resistance from effort
What is torque?
A type of pulley
A rotational force
A gear ratio
A linear motion
What is a gear train?
A machine that uses pulleys
A system of levers
A group of gears working together
A type of crank
What happens when two gears touch?
They rotate in the same direction
They stop moving
They rotate in opposite directions
They increase in size
What is the purpose of an idler gear?
To increase speed
To change direction
To reduce torque
How is gear ratio calculated using teeth?
Teeth of input gear ÷ teeth of output gear
Teeth of output gear ÷ teeth of input gear
Teeth × diameter
Teeth ÷ rotations
If the driver gear is larger than the driven gear, what happens?
The output rotates slower
The output rotates faster
The gears stop
The torque increases
What is a compound machine?
A machine with one part
A machine made of multiple simple machines
A machine that uses electricity
A machine that only uses gears
What does a crank do in a machine?
Converts rotational force to linear force
Stores energy
Stops motion
Measures torque
What is the role of the belt in a pulley system?
To reduce friction
To make the pulleys rotate in the same direction
To increase torque
To store energy
Why is mechanical advantage important in machine design?
It makes machines look cooler
It helps predict how machines will behave
It reduces the number of parts needed
It increases the cost of machines
