Experimenting with Mechanical Advantage

pulley Try the pulley simulator program and answer the questions

How much force is needed to lift the weight for the MA=4 pulley?

 

How much force is needed to lift the weight for the MA=3 pulley?

 
How much force is needed to lift the weight for the MA=2 pulley?
ramps Run the ramp simulator program, experiment and fill in the table
Ramp Ramp 1 Ramp 2 Ramp 3 Ramp 4
Rise Height 45 30 22.5 18
MA        
Force needed        
For the car to
travel 10 vertically
How far does it travel total?		        
         
         
gears Run the gear simulator program
  1. How many teeth are on the big gear?
  2. How many teeth are on the smaller gear?
  3. How much force does it take to lift the weight off the ground?
  4. How far will the weight lift upward if the handle is pulled down 150 inches?
  5. What is the equation that calculates the mechanical advantage for this system?
