4: Experiment Twob: Assessment of the moment of force. A third and fourth weight had been applied in order to achieve a system of four forces in equilibrium.įig. The central ring representing the center of gravity was affixed by a central post. Initially there was fifty grams applied at 30° and one hundred grams applied at 150°. The angular locations of the forces which were applied were equivalent. The pulleys had been affixed to a table edge in order to facilitate a variety of hanging forces to be applied toward a geometric center of gravity. The table enabled the assessment of angles. The total of all of the rotational torques which was tabulated regarding the geometric center of gravity must be equivalent to zero.Īn experimental force table was applied in the experiment.The total of the external forces is equivalent to zero.These objects can be delineated by the following conditions: Static equilibrium is referenced by objects at rest. The goals were to determine the geometric center of gravity and to tabulate the values corresponding to the rotational torque at distinct points of the object. In the establishment of the model, the geometric center of gravity was ascertained regarding the rigid form. There had been a rigid object, which received support at one of the ends and served as a rotational axis. The experiment had been achieved by means of three components. The goal of the experiment had been to review the participation of forces and torque which react on objects that are in the condition of static equilibrium. The value of the torque forces must also be equivalent to zero in order to fulfill the conditions of static equilibrium. The rotational tendency is delineated as torque.

This is reliant on the dissemination of force or mass. In the case of an object being at rest which possesses an axis, it may have the rotational tendency. The object is considered to be at rest when the sum of the net forces exerted total to zero.

Static equilibrium is a condition which occurs when objects are at rest. The mass of the meterstick will be determined later.Relation of Global Warming and Extreme Weather Condition The location is called the center of gravity. This does not determine the magnitude of the force of gravity, just its location. Since the forces on the stick must add to zero and the stand can only exert a force on the knife edge, it follows that the effect of gravity on the meterstick is a single force, acting down at the point on the meterstick above the knife edge. Note the hanger's location when the stick remains at rest. Moving the hanger one way will make the imbalance worse, while the other way makes it better. Although this is somewhat inconvenient, the system works much better this way.) If the meterstick does not remain horizontal, move the hanger slightly until it does. (You should attach the hangers with the adjustment screw on the bottom. (For more details on this, please see your lecture notes or consult your text.) Before We Begin Slide the pivot hanger to the 50 centimeter mark and place the knife edge on the grooves on the stand. The force being exerted on the meterstick by a hanging mass, m 1, has magnitude, m 1 g. There are additional hangers, that can be placed at any points on the meterstick, on which you can hang various masses. The hanger has a knife edge and the stand has a groove into which the knife edge fits. This hanger will be referred to as the pivot hanger. The Apparatus You will have a meterstick which has a hanger on it so that it can be balanced on a stand.
