Abisha Mascorro Mr. Rutherford CIS-Physics January 13,2017 Equilibrium amongst 3 masses Two equal masses at each end are suspended freely in the air with a force of tension that connects to a center weight, creating an applicable distance that is measurable. Therefore, as masses are added to the center will it create differences in distances between the strings? My group’s prediction consisted of past physics knowledge that was applied stating that the more mass (kg) that is added (cause) the measurement of distance will gradually change (effect). Our prediction consisted of measurable facts that backed it up with known physics. Such as Newton’s first law that states if a system is stationary than all the forces are balanced as it is illustrated below, showing how the strings tension in each of them is the same. Since all the masses are stationed in static equilibrium, the force pulling in the middle explains how they must be balanced. This is where I noticed that each exerts equal forces, due to the third law pair that explains how an action-reaction pair works. Knowing this, we proceeded with our provisions of dealing with the distances that we had to overall compare it with the masses. The procedures for this lab consisted of tools that will be essential to proceed with our findings. Materials such as a meter stick, logger pro with computer, two 500 kg.weights, different sets of weights in (kg) for mass c, two pulley clamps, and a long string. Meanwhile, we set up our materials, one of my group members provided us with their lab notebook that included the equation that was done by using an FBD and FAD as a simple one is provided below.

    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.
