Yeap at 4:43 you said the components added together should give the force so I assume that means that fy+fx = 40 But when we found out the value of fy and fx it was more than 40 or did u mean something else by saying that?
That is only as a vector addition. Here we are only dealing with the magnitudes of the force vector, so adding the magnitude of fy and fx will not equate to F. We will need to use Pythagoras theorem to link all three sides of the triangle.
thank you for helping me sir
Thank you sir,that was clear and genuine explanation
Thank you for the kind comment 😊
Thanks tch, I feeling that I have been learnt very easily and understand after watching your video
I'm very happy to hear that. 😊
Keep up your good work!
Very informative video, thanks
Thank you for dropping a comment. Glad it was helpful. 😊
@@MrRuelTuition it was very good infact I am sure I passed the test I had today, keep making more videos👏🏾
Thank you Mr tuition
You're welcome 😊
thank you sir, very helpful : )
You're welcome! 😊
sir to answer this questions , i can use the sin and cosine rule from addmaths?
By right any method is fine as long as you can produce the correct answer. However, for SPM Physics I will advice against using sine and cos rule.
1 question sir, on the first example you said that fy + fx = F but they didnt so why is that or am i understanding something wrong
Hi! I'm not sure which you are referring to. Could you please tell me the time stamp?
