WorksheetsMechanical Advantage and levers review
Total questions: 10
Worksheet time: 5mins
All of the following are simple machines except:
Wheel and Axle
Lever
cam
pulley
The 3 components of a lever are:
Effort, Load and output
effort, fulcrum and output
fulcrum, output, bar
none of these
How much a simple machine modifies/changes the input force is called its:
Fulcrum
mechanical advantage
Output
All of these
The type of mechanical advantage that can be calculated using forces is:
Actual
Ideal
neither of these
both of these
IDEAL mechanical advantage is calculated using:
forces
weights
distances/dimensions
the Pythagorean Theorem
A lever with an output force of 10 N and an input force of 5 N would have a mechanical advantage of:
50
2
5
none of these
A see-saw is an example of which class/type of lever?
1st class
2nd Class
3rd class
4th class
A good example of a 3rd class lever would be:
your arm
a fishing pole
both of these
neither of these
The formula for calculating the ideal mechanical advantage of a lever is:
distance of effort divided by distance of resistance
distance of resistance divided by distance of effort
output divided by input
none of these
In order to lift a heavy load with a lever, one should move the fulcrum:
closer to the load than to the effort
closer to the effort than to the load
right in the middle between the effort and load
