TRANSLATIONAL & ROTATIONAL EQUILIBRIUM Introduction/Objective: For maintenance on large buildings, scaffolding can be hung on the outside. In order for the scaffolding to support workers, it must be in translational and rotational equilibrium. If two or more forces act on the scaffolding, each can produce a rotation about either end. Therefore, either end can be referred to as a pivot point. Scaffolding with uniform mass distribution has all the mass concentrated at its center. In translational equilibrium the object is not accelerating; thus , the upward and downward forces are equal. B In order to achieve rotational equilibrium, the sum of all of the clockwise torques must equal to the sum of all the counterclockwise torques as measure from the pivot point. That is, the net torque must be zero. In this lab you will model scaffolding hung from two ropes using a meterstick and spring scales, and use number to measure the force on the scaffolding. Materials: Meterstick Two spring Scales Two Ring Stands Two Clamps Two Meterstick Slides. 500-gram Mass 200-gram Mass Procedui > Note: The left spring scale will be considered the pivot point for this lab, therefore the lever arm will be measured from that reference point. 1) Place the slides on the meterstick, one located at the 10-centimeter mark and one at the 90- centimeter mark.
