What is the Motion of a Bifilar Pendulum?

AI Thread Summary
A bifilar pendulum consists of a body suspended by two parallel strings, allowing for various types of motion, typically torsional. The motion can be forwards and backwards, side to side, or rotational, depending on the setup. It is commonly used to measure the moment of inertia, making it relevant in physics and engineering applications. The discussion also emphasizes the importance of relating the bifilar pendulum to real-world scenarios in a report. Resources and links were shared to help understand its applications better.

Heyy guys,

I have and EEI to do on a bifilar pendulum. Essentially a bifilar pendulum is acheived by two parallel strings instead of one. I have already built the device but don't know how the motion should be. Shourd it be farwards adn backwars? or side to side? or rotate?

Thanks in advance:)

welcome to pf!

heyy joelKID984! welcome to pf! :smile:

"bifilar" simply means "having two threads", so it could be used in any of those three ways

but i believe it's usually operated as a torsional pendulum …

for pictures, do a google image-search for "bifilar pendulum" :wink:
 
how does a bifilar pendulum relate to the world

ok,

im doing an EEI on a bifilar pendulum and I am on one of the lest sections of the report that quite important as it shows critical thinking. i have to discuss how the bifilar pendulum relates to the real world.

essentially a bifilar pndulum if a pendulum with two parallel filaments attached to a body instead of one. i know that a bifilar pendulum is used to measure moment of inertia, but how can it relate to the real world.

Thanks,
Joel

This site , I think beautifully explains your case : http://www.egglescliffe.org.uk/physics/gravitation/bifilar/bif.html

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
