Simple Machine-Lever

I will have the will have the probability to learn about the mechanistic favor of machines and how to calculate the skill of a machine. I will construct first, second, and third var. levers using both a ruler and a sentence stick, test different despatchs in the levers, use a spring scale to measure force, and calculate the mechanical advantage of each type of lever.
The objective is to explore the concept of mechanical advantage using levers.
In experiment 1 constructed a lever with a round pencil, a ruler and basketball team quarters. I lay the first quarter at 4cm apart from the fulcrum, which is the commit, and on the opposite side of the fulcrum I framed single quarter trying to balance the lever, which is the effort. I consequently placed a quarter one by one supra each other at the load until I reached the after part quarter and it became impossible to balance the lever, recording my info on Data Table 1.
Experiment 2 part 1, I constructed a first class lever. To perform this procedure secure and taped a string around a measuring stick stick at the fulcrum point for each setup. I then(prenominal) suspend the meter stick by the string so that it hangs freely. Possible places to suspend it from include a clothes rod, a shower curtain rod.



I make a load pan from a paper cup by attaching a piece of string to the rim of the paper cup in such a way that the cup can yield weights while being suspended from the meter stick. I made a first class lever by suspending the load pan starting at the 20-centimeter mark then ever-changing it later to 10cm then 5cm. Taped the string in place so the load pan does not slip. I then placed a known weight (150 200g) into the load pan. then(prenominal) I Attach the 500-g spring scale at the far end of the meter stick so that the weight intent hook is at the bottom. When the assembly is steady, gently pull descending(prenominal) on the spring scale until the meter stick is direct and parallel to the floor. Read the scale to measure the force requisite to balance the load. I then recorder all data values...If you want to get a full essay, order it on our website: Orderessay
