Thank you sir bcos its ur videos i have been using to pass my practicals God bless u sir

You save all 🙏🤝. More bless 👍

[@teamfcglobal6833]

You're doing a great job Sir 🎉👏 👏 👏 👏 👏 With regards to this year Neco's practical on Mechanics... Its quite dicy😢... Reason been that the thumb pins required is #5 meaning ~4 for the drawing paper 📜 & ~1 for ???🤔... It has to be for the single pulley system then😅 So we will have to be open for either 1. Triangular law of forces Sn/m/y/AO/(y/AO)/ °/¢= (90-°) A graph 📈 of either ~ M vs y/AO or ~y/AO vs M or ~ M vs cos¢ and evaluating K = s/2 2. Efficiency of a single pulley system; W=30.0g E = (M.A /V.R) x 100% ~Where M.A = Load/Effort = W/M (i e m=10g,20g,30g..) V.R = effort distance/load distance V.R= d2/d1 (approximately equals 1) Values to record Sn/m/d1/d2/I=(d2/d1)/x=(W/m) A graph 📈 of either ~ d2 vs d1 equals v.r Slope=∆d2/∆d1 = 1.0 ~ X vs I = s Locate v.r from the graph at 0 point/intercept ; ans v.r=1.0 Evaluate K= s x 100 (Value of Kexpressed in %) Just my thoughts 💭 Sir 🙏.... You're the best😅 ❤❤❤❤ Thanks so much Boss 🎉

Thanks for practical, please are the students going to submit the diagram drawn on the paper?

[@vindalsacademy]

Yes they have to submit

[@adewumiblessing1031]

Ok

[@Omez213]

Excellent job. How much is the pulley? Around Oshodi?

[@vindalsacademy]

I don’t really know but call a laboratory vendor. Or bookshop they will tell you where to buy it. Thank you for reaching out.

[@chinazaanastesia3862]

Please why is it not concluded, do you have continuation of it

[@chinazaanastesia3862]

Please when they said evaluate K=58 What should be the answer

[@Campus_lifestyle]

Single fixed pully was required... I think it's M.A and VR EXPERIMENT

[@vindalsacademy]

This one is not out of place. I will still perform the other experiment if I have time.

[@Anti-boredomz]

This is the most comprehensive explanation you'll find on the internet and that's how grateful you are for the resources put in this video 😒

[@madesolaokechukwu]

No it is not

[@vindalsacademy]

Thank you sir. For seeing this video very helpful.

[@vindalsacademy]

There is always a room for improvement sir. And I am always working to do better on my subsequent videos

[@madesolaokechukwu]

Can i see how u plotted the readings and graph

[@diamondadekoya2975]

But sir in the specimens given to us by neco they put twine instead of using thread also they said we should use one fixed pulley and not a clamped pulley and what was the table of values and slope for the practical sir

[@vindalsacademy]

Yes, they basically mean the same thing. But don't worry I will do another experiment with twine (rope)

[@idikapaul2024]

What's the difference?

[@idikapaul2024]

You are doing great Sir, this is similar to 1999 WAEC question

[@madesolaokechukwu]

Yes 1999

[@AdepojuFaith-d2f]

Sir does this mean that you would have to use different masses on different papers to get the reading of is it the same paper and also Sir can we use any side of the pulley since only one pulley is used

[@vindalsacademy]

A well organized and effectively done practical can still have two or three on the same paper. But you need to organize your work very well. Thank you for reaching out.

[@olaitangabriel7902]

The materials given, they only mentioned 1 fixed pulley but you are using two pulley, why?

[@vindalsacademy]

You didn’t watch the full video.

[@humpheryolu5468]

I'm guessing he used it to engage the other end of the twine, straightening it

[@vindalsacademy]

Exactly. Thank you for reaching out. Don’t forget to subscribe, like and share the video to reach other people. And to encourage me to be better. Your comment will be attended to if not in this video but in a subsequent ones

Sir why use two pulleys?

[@vindalsacademy]

If you notice the other pulley was not used. It’s just a fixed point. Thank you for reaching out. Don’t forget to subscribe, like and share the video to reach other people. And to encourage me to be better.

[@oghoghoudoko9372]

What is the gram of the suspended mass

[@vindalsacademy]

I am using 100g. But NECO question will guide you on what to do. Thank you for reaching out. Don’t forget to subscribe, like and share the video to reach other people. And to encourage me to be better. Your comment will be attended to if not in this video but in a subsequent ones

Sir I don't really understand what you are doing because I don't really like physics practicals. Sir can you please help me? 🙏😭😭😢

[@vindalsacademy]

If this video can't help you it means you need an extra lesson. Enrol into my online physics class

[@odenandrew4865]

How can one get the pulley

[@vindalsacademy]

You can buy it in any physics laboratory shop. Let me ask, which area are you?

Thank you sir for conducting the experiment but sir pls do cheat for this particular experiment ok?

[@vindalsacademy]

Sure now I will run it

[@Melawoj]

@@vindalsacademy thank you sir you have really helped me in these exams

[@AYEGBAAKOH]

Can a force board be use for this?

[@vindalsacademy]

Yes of course

[@obinnabede6718]

Its easier to draw your horizontal line and find the middle. Draw the vertical lines before clipping you pulleys and fixing on retort stand. Secondly, no need of removing the constant mass ie 30g at interval,, just hang the the pass direct on the twine, starting with lesser weight of 20g to higher weight.

[@desmondanthony7135]

Is this proper in this nexo exams .. is it expo or allowed

[@vindalsacademy]

I wish I have seen the question I would have done a video on. But I am not sure if NECO will bring the same question. This is just a guide. I wish you good luck Thank you for reaching out.

[@teamfcglobal6833]

Must it be a large drawing paper...😢 Plsssssss how about using an A4 paper.... Since you're using a big drawing paper..😢 🤔 i guess it has to do with the large Mass right i.e >50g...

[@vindalsacademy]

This is the standard graph 📉 paper for SSCE. It's the same thing since 2cm is the same for all

[@GbadamosiHabeeb-xc3vg]

Why using two pulleys when they asked for only one pulley

[@vindalsacademy]

You didn’t watch the video

[@GbadamosiHabeeb-xc3vg]

I watched till the end

[@vindalsacademy]

I didn’t use the other pulley. I used only one for the practical

[@EternalScienceAndTech]

This practical is very simple but you are making it look difficult.

[@vindalsacademy]

Thanks that’s all I have to offer at the time
