Abstract
The aim of this experiment is to determine the conditions of equilibrium, to locate the centre of gravity, and to demonstrate rotational equilibrium. The experiment was performed by doing a series of activities such as the use of a force table, strings, and a force board. Results were obtained theoretically and experimentally.
Introduction
Equilibrium is the state of an object when no part of the object is accelerating. there are two common types of equilibrium: static equilibrium and neutral equilibrium. Equilibrium usually is related to potential energy, for a system to be at equilibrium it must maintain the balance between the two types of mechanical energy: potential and kinetic. The first equilibrium: static means that the system is in a relatively low (relatively means that there could be lower energy but the current states is a local minimum), thus small disturbances to the system will be returned to its original equilibrium. The other type of equilibrium is neutral equilibrium, the relative energies of the system is constant, thus disturbances to the system will move the system but it will remain at the same equilibrium value, and the system makes no effort to return to its original state.2 Equilibrium is composed of
two conditions (1) Net force is equal to zero and (2) Net torque is equal to zero.
Torque is a measure of how much force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point. The distance from the pivot point to the point where the force acts is called the moment arm. Torque is simply the product of force and the moment arm.
The objectives of this experiment is to be able to determine the conditions of
