By using a motor
Which of the following is NOT a key vocabulary word related to linkages?
Voltage
Input
Pivot
Mechanical advantage
What is an example of rotary motion?
A pendulum in a clock
A wheel turning round in a circle
A paper trimmer moving in a straight line
A saw moving forwards and backwards
What does "pivot" mean in mechanical systems?
To move in a straight line
To turn on a central point
To swing side to side
To move forwards and backwards
A student wants to design a mechanism where two levers move in response to a single input. Which component should they use to connect the levers?
Linkage
Spring
Pulley
Gear
What is the definition of linkages in mechanical systems?
Toothed wheels that fit together
Rigid components (like rods or levers) connected to transfer motion
Flexible cables used to transmit signals
Springs that store energy
A designer wants to change the speed of rotation in a machine. Which mechanical component should they use?
Linkage
Gear
Spring
Pulley
If you need to convert rotary motion into linear motion in a machine, which component would you most likely use?
Linkages
Gears
Wheels
Belts
Which of the following best explains why gears are important in bicycles?
They change the speed and direction of rotation, making the bicycle easier to ride.
They store water for the rider.
They provide a place to attach decorations.
They make the bicycle heavier.
What is the main purpose of a gear in a machine?
To store energy
To transfer motion and change speed or direction
To measure temperature
To add colour to a machine
What is a pulley used for?
To change the direction of a force
To light up a machine
To increase the weight of objects
To measure distance
If a small gear drives a larger gear, what happens to the speed of the larger gear?
It increases
It stays the same
It decreases
It spins in the opposite direction only
What type of pulley system gives a mechanical advantage to lift heavy objects?
Fixed pulley
Movable pulley
Single wheel pulley
Frictionless pulley
What happens if two gears of the same size are connected?
The speed of rotation changes
They rotate at the same speed but in opposite directions
One stops moving
They rotate in the same direction
Why are pulleys often used in cranes?
To change the colour of loads
To make lifting heavy objects easier
To increase the weight of objects
To reduce the size of loads
What is the purpose of teeth on gears?
To lock gears together so they don’t slip
To make the gear heavier
To decorate the gear
To store energy
In a belt and pulley system, what does a larger driven pulley do compared to a smaller driver pulley?
Increases speed
Decreases speed but increases torque
Stops movement
Makes the system lighter
Which of these is an example of a pulley in everyday life?
Bicycle chain
Flagpole rope
Door handle
Electric plug
How do gears help change the direction of rotation?
By using flat surfaces
By meshing two gears with teeth in opposite directions
By increasing weight
By changing the material of the gear
