Simple Machines - Levers Quiz

What is a lever?

• A musical instrument

• A type of animal

• A simple machine

• A type of food

What is the fixed point called in a lever?

• Bar

• Effort

• Load

• Fulcrum

How do levers make work easier?

• By increasing the distance moved by the effort

• By reducing the effort required

• By reducing the distance moved by the effort

• By increasing the effort required

How can a lever achieve making work easier?

• By moving the load closer to the fulcrum

• By reducing the distance moved by the effort

• By moving the fulcrum closer to the load

• By applying the effort further from the fulcrum

How many types of levers are there?

• Four

• Three

• Five

• Two

In which type of lever is the fulcrum between the load and the effort?

• First class levers

• Second class levers

• Third class levers

• Fourth class levers

What changes the direction of the effort in a first class lever?

• Load

• Fulcrum

• Effort

• Bar

When is work the easiest in a first class lever?

• When the effort is applied to the load directly

• When the effort is applied to the bar as close to the fulcrum as possible

• When the effort is applied to the bar as far from the fulcrum as possible

• When the effort is applied to the bar at the midpoint of the fulcrum

What is the fulcrum in a second class lever?

• Between the effort and the load

• Between the load and the effort

• At the midpoint of the effort and the load

• At the midpoint of the lever

What is the direction of the effort in a second class lever?

• Perpendicular to the force applied to the load

• In the same direction as the force applied to the load

• At an angle to the force applied to the load

• Opposite to the force applied to the load
