In this video I will equate the simple harmonic motion of a block attached to a spring to the rotational equivalent of the torsional pendulum.

Hi, I am doing a research project about the torsional pendulum. I will be finding 'k' through an experiment. My teacher has asked me before doing the experiment to give him a literature value of 'k' so I can then compare the experiment result with such literature value. I cant find the literature value of 'k' anywhere. Can you help me?

Hi, Thank you for your video. i have few questions: so the dtheta2/dt2 is the second derivative of the angle? also, how do you find the first derivative of angular velocity? ( is that basically the theta (t)=theta max *sin(wt)?)
@MichelvanBiezen
@MichelvanBiezen 2 жыл бұрын
The answer to your first question is yes. The answer to your second question is: first find the angle with respect to time via the sin of cos function. Then take the first derivative to find angular velocity. Then take the second derivative to find angular acceleration. You'll need to know how to find the derivative of a cos and a sin function.

Sir, when the torsional pendulum setup is immersed in water, because there would be an opposing force due to viscosity, the time period would increase. Is my thinking correct?

Really useful series of videos, thanks a lot. I have a question concerning the units of the torsional constant. If torque is N*m and give the equation torque= constant * angle, should not the unit be N*m/rad?
@MichelvanBiezen
@MichelvanBiezen 5 ай бұрын
Radian is actually a "non-unit" and can therefore be left off. But for clarity, and the avoidance of confusion it is a good idea to add it. (But many books don't)

hi may i ask if Period and mass of the torque disc is inversely proportional? (Since for the torsional pendulum, since Period is equal to (2 pi)(square root of K divided by I), and I is proportional to mass and radius) If this is the case, does it mean that the higher the mass the ower the period? thanks so much and loveee ur videos by the way!

The period is proportional to the square root of the mass.

Firstly, thank you so much for your contents. I have a question: I see the equation of x as x ( t ) = A cos ( ω t + ϕ ) in my textbook and some sources in the internet. But as in that video and some other sources it is written with sinus. What is the difference? How would we decide to use which trigonometric function?
@MichelvanBiezen
@MichelvanBiezen Жыл бұрын
The choice of sin or cos only depends on the initial conditions at t = 0. If the displacement is maximum at t = 0 choose cos. If the displacement is zero at t = 0, and moving in the positive direction use sin. This will not affect the period, frequency, etc.
