2. You looked at a couple different kinds of simple machines in the lab today (and in lab 2). Imagine you needed to move a 500-kg limestone block out of your driveway. Without math or details, what simple machines might you use, and roughly what kind of mechanical advantage would you need? [insert response here] 3. Think about situations where we use levers (other than your arm). How does increasing or decreasing the length of the effort arm and the resistance arm affect the value of force being applied? Provide a specific example from your life where you might use a first or second class lever. Roughly estimate the location of the fulcrum, sketch a picture, and provide your calculation for the ideal mechanical advantage you would gain from this situation.
