29. 28. What do machines actually do? Work makes work easier by changing the amount of force you exert or the distance over which you exert the force.

30. Mechanical Advantage and Friction

31. 29. Explain what would happen to the input and output if we took all of the friction away? If the friction is taken away, then the input and output are equal.

32. Pulley

33. 30. What is the advantage the pulley provides? The advantage a pulley provides is that it changes the direction over which a force is exerted.

34. 31. How do you calculate the force exerted? To calculate force exerted you divide output by input.
