Physics Practicals:Determination of Mechanical Advantage & Velocity Ratio of a Single Fixed Pulley

[@OnweBlessing-wu2mn]

Thank you so much sir, u made it more easy for me in the exam God will bless u 🙏

[@bestsciencebrain]

You are welcome. Check out the new video that is about to drop now

[@Al-ameenMuhammad-ut1gm]

Good day sir, I think this practical exactly like previous years neco 2020

[@bestsciencebrain]

I have no idea of the question they asked in 2020

[@OdebiyiMichael-wp1ej]

Please do you have the 2020 neco question?

[@abdulkarimmusa7895]

You made it for us all. More bless Sir

[@bestsciencebrain]

We appreciate

[@mercyngbede-nq6ws]

Great job, well done

[@bestsciencebrain]

We appreciate

[@YemiAyinde]

Good work, well done

[@bestsciencebrain]

We appreciate. Thanks

[@anotyikenna]

Thank you sir😊

[@bestsciencebrain]

You are welcome

[@darlingtoncopurum7430]

What kind of twine do we use? The rope am using is falling with the masses.

[@bestsciencebrain]

Check out the newest video

[@NazyStudio25]

Pls Sir, Are we submitting the drawing paper for this particular practical?

[@bestsciencebrain]

No. Drawing paper is submitted in number 2 question which involves rectangular glass block

[@akanjisaheed5876]

Well done sir, please is there a specified length for the twine and the iniatial distance of the twine from the fixed end of the pulley to the fixed mass M

[@bestsciencebrain]

Thanks for your comment. 1 m length of twine. The initial lengths of the twines of masses from the pulley center were not measured, however the twine attached to W, the 30 g mass was made longer.

[@akanjisaheed5876]

@@bestsciencebrain Alright, thanks sir

[@darlingtoncopurum7430]

The rope or twine am using is just falling with the masses when I increase the mass on the other end. What kind of rope do we use?

[@udemejohnson9602]

Pls sir i want to ask where is this question repeated in past question

[@bestsciencebrain]

Not a past question

[@PhilomenaOkonUweh-xs7yk]

Good day sir, plz show us a video of how to manipulate the practical without doing the practical. Thaz

[@AndersonNathaniel-ns6hn]

just take his readings and memorize it, the main thing is the plotting of the graph, I am also a Physics Teacher

[@AndersonNathaniel-ns6hn]

however, if you want to learn to manipulate, remember that as d2 which is the distance for the effort decreases, the d1 which is the distance of the load increase, so just do an increment between 6 or 6. something between d2 and d1. For example, the first d2 was 19.00, if I add 6.20 to 19.00, I will get 25.20 for my d2

[@augustineogbebe5123]

Great job sir If am correct sir which means drawing paper is no mandatory

[@bestsciencebrain]

In the experiment, drawing paper is not mandatory. However, if we want to measure the vertical displacement of the load and the effort, then we need the drawing paper. The position of each end of the twine is marked on the drawing paper before hanging the loads and marked after hanging the loads. The distance between the original position and the new position when the masses are hung gives the displacement in each case.

[@jasperchigozie9310]

The masses are not hanging freely; they are touching the board. Don't you think this will have an effect on your reading?

[@bestsciencebrain]

This is not motion under free fall. A flat surface is needed for the pulley. Thanks

[@MarkEroh]

Good morning Sir, pls is they a reason why you're not taking the reading of the meter-rule from zero (0) point to the center of the pulley?? Secondly ur camera man should take a closer video of the experiment bcos the video is a little blurry in some instances. Tnks for your insight

[@bestsciencebrain]

Thanks for your comment. The reading was not taken from zero because the board was not suspended using retort stands. Had it been retort stands were used, then it would be ok.
