@erobz @kuruman @BvU @Steve4Physics @haruspex @Delta2 Hello everyone! Sorry it's been a while, I was caught up with the other assignments and barely had any time to work on this report. Here's the summary of the experiment again. The latest update is that the theoretical model of this...

@erobz @kuruman @BvU @Steve4Physics @haruspex Thank you so much for your help, I will try to come back by next Wednesday hopefully. It's really insane how I can assemble all the physics gods within a few clicks. I love the internet HAHAHAHA

It is true that there is a non-zero y-intercept but it is quite low tbh (-0.0156). Which means that ##D = L\sin\beta## is in fact working right

Oh, I understand what you mean now. So when you plotted the % discrepancy graph against measurement number, the discrepancy was always able to remain below 100%? That's interesting. How do I determine the overall % discrepancy of the experiment though? Do I take the average of the % discrepancy...

Oh no:( Did your email get accidentally leaked?

😂 I used a 2-digit display electronic balance but I used an online Weight calculator which used a very precise value of g. I will round it off to correct d.p

Sorry for the confusion. The discrepancy is what we call the %error here. My plan was to experimentally find the length of the string and compare it with the actual value i.e. ##Percentage error=\frac{\left | {L_{Exp}-L_{Actual}} \right |}{{L_{Actual}}}\times 100$$##. I am not so sure what you...

The weight of the sphere is ##0.0738N## The weight of the screw is ##0.00949N##

When I took the inlet area to be equal to the outlet area, the percentage error turned out to be 620%. I didn't get to change ##\theta## yet. I most probably won't until next Tuesday as I have 2 important deadlines coming up soon:(

In the tracker app, you can calibrate the scale of length in the video by putting an object of known length in the background and telling it its length. Once I calibrated the length, I used the screw as the reference point. I recorded the x-coordinate of the screw at its initial position...

@erobz @kuruman @haruspex What I meant was the screw was aligned with the line of the string when the sphere was in its initial position. There’s definitely some torque involved once the sphere reaches the equilibrium position. In fact, solving for moments was my initial approach but I didn’t...

@erobz @BvU I just realised my ridiculous mistake. For the mass of the sphere, I didn’t want to disrupt my set-up incase I wanted to collect more data. So, what I did was to look for a sphere of similar size and material and used its mass for my calculations which was 42 grams. I found a spare...

Oops, I made the document in a hurry yesterday 😅 I will try to get everything fixed tmr. I initially used powers of 10 and rounded off everything to 3sf but I thought people who are reading it would prefer to have full data

@BvU @Steve4Physics @haruspex @kuruman @Orodruin Sorry, I forgot to mention that I made a document summarising everything that has happened so far. I will make another thread. Meanwhile, Please look through this document

yea:( It's tough to make any of those assumptions as the flow rate is not even constant to begin with. I think it is reasonable to assume that the center of the sphere lies on the string though, The string was attached to the sphere at the exact middle point on the top using a screw
