Robert Crescenzi Lab #112 10/13/10 1. Title: Static Force Equilibrium--- Force Table 2. Objective: -To confirm the condition for static equilibrium is that the vector sum of forces is zero. -To experimentally test the vector nature of force. -To practice manipulating the vectors. -To attain better understanding of vectors. -To find unknown tensions and directions in a system of strings connected to a central ring. 3. Background: R=(R(x)^2 + R(y)^2)^0.5 where R(x)=Ax+Bx+Cx and R(y)=Ay+By+Cy 4. Procedures: -Set up according to Figure 3 in lab book. -Then add weights to any or all of the 3 hanging masses and move their position around the circle until it reaches static equilibrium (it reaches equilibrium when the ring in the center is not touching the pin). -assign each hanging mass a letter, a b and c so that you will have (force of tension) Ta Tb Tc and (angle from x-axis) @a @b @c. -Find the experimental value for each of the terms in the previous step.

### What students are saying

• 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.
