Analysis: The Lightest Way To Lift Up A Heavy Object

The Lightest Way to Lift Up a Heavy Object - David Choung
Have you ever had a time where you had to lift a heavy object into a pickup truck, but couldn’t do it? Did anybody suggest using a pulley or an inclined plane? In this paper, you will get to know why someone would suggest using a pulley to get a heavy object onto the back of a pickup truck. To use a pulley you first have to know how a pulley works. A pulley is a way to lessen your effort picking up the object. There is a term called mechanical advantage you would need to know also. It basically means how effective the pulley is. So for example I wanted to pick up a 100-pound box, and I had a pulley with a mechanical advantage of 2, the mechanical advantage would come in affect and I would only have to supply 50 pounds of force to pick a 100-pound box. So it is basically dividing the mechanical advantage to the weight and that would be how much force you needed to supply.
There are a few types of pulleys, but to have the best pulley, you would use the block and tackle. The block and tackle is a combination of different pulleys. The block and tackle is the best because it can contain the highest amount of mechanical advantage.
You would do that because you would have to make the pulley higher than the truck. You would make the block and tackle by combining single fixed pulleys and single movable pulleys. Single fixed pulleys are pulleys that you put your weight on one side in order to raise the object. This pulley would contain a mechanical advantage of 1. Single movable pulleys are pulleys that would have a mechanical advantage of 2. After making the pulley, you would hook it up to the heavy object and your friends and you would pull on the rope that would be on the end of the pulley. The object would move and you would move the truck towards it and gently drop it down on the truck. Then you would be
