E204: Torque: Second Condition of Equilibrium
E204: TORQUE: SECOND CONDITION OF EQUILIBRIUM
IBAÑEZ, Jonen Lery L.
OBJECTIVE
A torque is an influence, which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm.
In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the second objective is to ponder second condition of equilibrium’s use and importance.
MATERIALS AND METHODS
Setting up the apparatus given with the following materials: Phywe model balance, Pasco Scientific Mass and Hanger Set (ME-8967 & ME-9348), Meterstick, Protactor, Weight Pans and Spring Balance.
(Figure 1. The following materials needed for accomplishing experiment 204.)
The first part of the experiment, which is the determining the weights of the pan. Setting up the apparatus, make sure that the model balance is stagnant to avoid errors. Mark the pans as P1 and P2 and place the certain weight indicated on the table on the P1 only and adjust the pans on the beam so that the system is in equilibrium. Measure L1 from the center of the beam to the P1 and L2 from the center of the beam to P2. Now remove the weight from P1 and add the certain weight this time in P2 and adjust the pans again for equilibrium. Now measure L3 from the center to P1 and L4 from the center to P2. You get these equations in solving for the actual value of P1 and P2: for equation 1 and for equation 2.

The second part of the experiment, which is determining the force needed to be in equilibrium. You only need a single pan on this part adding 50gm weight at the left side of the beam. Place the spring balance on an upright position and now pulling it. See to it that the angle of
