Introduction : In this experiment, we were asked to perform a series of tasks that would help us draw several conclusions about forces and force vectors. We were asked to prove that forces can be added together in the same way that displacements are added (making them vectors), demonstrate how an arbitrary force is equivalent to its vector components, and demonstrate how to add three arbitrary forces together mathematically using the general method of vector components. In order to properly address these objectives we were asked to perform multiple experiments using a force table. With three movable pulleys around the circumference of the force table, all of which were connected by string to a ring centered at the middle of the circle, we then applied different masses to the pulleys and did so until the ring was in equilibrium and thus not touching the vertical axle it was on. Keeping location of two pulleys fixed, we then proceeded to calculate the force needed to put the ring in equilibrium around the axle and did so as we moved the third pulley around for several intervals of 10º. After becoming more comfortable with experimenting with different forces at different angles we were then assigned three random angles and were asked to demonstrate how their net forces are equal to 0 and thus resulting in the ring once again being centered around the axle. Using the results from these experiments we were able to represent how multiple forces are directly related to one another in terms of their vector components. Procedure : For our first experiment we were asked to set up the three pulleys at three different angles. With one fixed at 180º and another fixed at 270º, we then proceeded to place the third pulley at 10º and applied 105g to its end, which would remain constant for the rest of the experiment. After setting up the pulleys we then determined the various masses needed at the 180º pulley and 270º pulley in order to hold the ring in equilibrium around the vertical axle. We proceeded to do this for intervals of 10º before stopping at

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
