B. Concepts or Principles Used Torque is the ability of a force to change the rotational motion of a particle. It is also called the moment of force. The Second Condition of Equilibrium states that for a body to be in rational equilibrium, the sum of all the torques acting on that body must be zero. Torque, moment or moment of force is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. The torque, specified about the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component. C. Relation of Data to the Concept or Principle of the Experiment The beam was balanced by putting masses on both left and right sides. We used different masses (as indicated on the data sheets) to understand more the concept of second condition of equilibrium.

### 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.
