| Question: | How do You find Mechanical Advantage for a can crusher? |
| Detail: | For a science project, we had to make a can crusher. Part of the lab is to find the mechanical advantage.. How do I do this? I know Mechanical Advantage= Load force devided by effort force..? |
| Reply: | You should look at this question as the mechanical advantage of levers in the can crusher (if it is made from levers, not motors or hydraulics). Let's assume it is made from levers. To calculate your answer, measure the distance from the point on the lever where your hand applies the force to the pin where the lever is attached. Then measure the distance from that same pin to the place where the can is located (the center of the can ). Divide the first number by the second. That is your mechanical advantage. It may be around 8 or 10. This method makes some assumptions, because you do not describe the crusher. |
