Mechanical Advantage

What is the equation for work

• F x D
• F = M x A
• y = mx + b
• 25 eevee eggs equals one evolution

How do you change the mechanical advantage on a first class lever?

• Making the fulcrum larger
• Changing distance between load and fulcrum
• Have more than one person push on the lever
• You can't...

Why does the lever have more mechanical advantage than the incline plane?

• The lever uses more force
• Newton's third law
• The fulcrum is stronger than the slope
• The incline plane has friction

What is the equation for Mechanical Advantage?

• MA=input force*output force
• MA=input force/output force
• MA=output force/input force
• MA= output force - input force

What is the mechanical advantage formula?

• distance x load
• output force divided by input force
• mass / direction
• whats mechanical advantage?

Which other simple machine is the inclined plane most SIMILAR to

• Lever
• Pulley
• Wedge
• Wheel and axel

if a load of a lever is 100 newtons and the force you apply is 20 newtons, what is your mechanical advantage?

• 120 newtons
• 50 newtons
• 2000 newtons
• 80 newtons

If a wheel is turned with a certain force, what will happen to the force on the axle?

• The force on the axle will be bigger than the force on the wheel.
• The force on the axle will be smaller than the force on the wheel.
• The force on the axle and wheel will be the same.
• There will be no force on the axle.

What happens when you have a short inclined plane?

• It takes less work to pull something
• It takes more work to pull something
• Nothing happens
• You have to accelerate to pull something

A pulley uses a wheel and axle to make lifting a load easier. T/F

• TRUE
• False
• Tacos
