Here, in this article, I will tell you the most important Viva Questions asked in Bifilar Suspension System Physics Experiment. Before beginning, I would recommend you to learn Torsion by clicking here as well as moment of Inertia by clicking here.
Bifilar Suspension System
What is the principle of bifilar suspension system?
Used to calculate the moment of inertia of any object at any point and also used to calculate the value of ‘g’.
Why it is called bifilar?
The term “bifilar” comes from the Latin words “bi” meaning “two” and “filum” meaning “thread.” In the context of a bifilar system, it refers to the two parallel wires or rods that support the oscillating mass.
What is a plumbline.
A plumb line is a tool with a weighted string that, when freely suspended, points towards the Earth’s center of gravity, indicating verticality.
This tool is commonly used in construction, surveying, and engineering to ensure that structures like walls, columns, or foundations are perfectly vertical.
What are the uses of bifilar suspension system?
Used in drones, aircrafts and suspension bridges etc.
What is the use of bifilar system in aviation?
It is used in vibration reduction, measurement of aircraft’s mass moment of inertia, etc.
What is a spring factor?
1) Restoring force per unit displacement (resistance offered by a spring when it is oscillated)
2) Spring constant is a measure of how stiff a spring is or how much force is needed to stretch or compress it. (Physical significance of spring contact)
