What is the purpose of the force table experiment?
The objective of this experiment is to find the equilibrant of one or more known forces using a force table and compare the results to that obtained by analytical method.
What is the force in the force table?
“The Force Table” is a simple tool for demonstrating Newton’s First Law and the vector nature of forces. This tool is based on the principle of “equilibrium”. An object is said to be in equilibrium when there is no net force acting on it. An object with no net force acting on it has no acceleration.
Why are pulleys used on a force table?
In order to redirect the force to act in a horizontal direction (i.e parallel to the surface of the table), chords and pulleys are used.
How do you find the resultant force of four forces?
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.
How will you know when the forces on a force table are balanced?
When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
What is the use of universal force table?
To verify the law of polygon for coplanar-concurrent forces acting on a particle in equilibrium and to find the value of unknown forces considering particle to be in equilibrium using universal force table. Apparatus: Universal force table with four pulleys, strings, standard weights. or rest.
What is the objective of the force table experiment?
The objective of this experiment is to find the equilibrant of one or more known forces using a force table and compare the results to that obtained by analytical method. Given two force vectors you will determine the third force that will produce equilibrium in the system.
How is the force table used in physics?
The force table allowed us to demonstrate when the sum of forces acting on the ring equals zero. Under this equilibrium condition, the ring, when released, remained on the spot. First we mounted the Force Table parallel to the working desk (horizontal position). We made sure it was level.
What causes an error on a force table?
Errors in the direction of the forces if the strings were not at 90 degrees tangent to the ring would have caused the greatest source of error. If the angles were the slightest bit off on the force table, this would have skewed the weight necessary to equal the forces.
What is the value of the pull on the force table?
The value of the pull (force) is mg, where g = 9. 81 m/s2 (recall Fw = mg). The force table allowed us to demonstrate when the sum of forces acting on the ring equals zero.
