Quiz on levers, pulleys, wedges, ramps

por Jeremy

What is mechanical advantage (MA) in simple machines?

Sum of input and output forces

Ratio of output force to input force

Ratio of input distance to output distance

Which simple machine changes the direction of force using a wheel and axle?

Lever

Wedge

Pulley

The lever where the fulcrum is between effort and load is which class?

Class I lever

Class III lever

Class II lever

What is the basic definition of a wedge?

A wheel that reduces effort

A lever with a fulcrum nearby

Two inclined planes used to split or lift

A ramp (inclined plane) primarily reduces required effort by:

Increasing weight

Increasing distance over which work is done

Decreasing friction

Does a fixed pulley increase the mechanical advantage?

Yes, MA > 1

Only when combined with a lever

No, MA = 1; it only changes direction

How is the MA of a lever calculated?

MA = fulcrum distance from ends

MA = effort arm length / load arm length

MA = load length / effort length

For a wheel and axle, the mechanical advantage equals:

Radius of wheel / Radius of axle

Radius of axle / Radius of wheel

Diameter difference between wheel and axle

Which factor primarily determines a lever's MA?

Length of the effort arm vs load arm

Material of the lever

Weight of the lever

With higher mechanical advantage, the effort must move:

Through a longer distance

Through the same distance

In the opposite direction
