Presentation includes: instructions for building a simple machines device and measuring mechanical advantage. Base Equipment. 2. SIMPLE MACHINES - LEVER. A lever is a rigid bar that rotates around a fixed point called the fulcrum.. The bar may be either straight or curved.. In use, a lever has both an effort (or applied) force and a load (resistant force). . Locate the part you are looking to replace in the appropriate exploded view drawing. Each part is given an item number.Find the item number in the left column of the appropriate chart and determine pa Learning Objectives. I can mathematically rearrange the mechanical advantage equation.. I can calculate . mechanical advantage . using the formula.. Actual Mechanical Advantage (AMA). The ratio of the output force to the input force in a machine. Measuring the actual forces on the machine..
