this is the best explanation ever. I have looked at countless videos of the right-hand rule and felt like I will never get it right. Then I found this masterpiece. THANK YOU SO MUCH.
Thank you, this video helped me out tremendously. I was having trouble finding when a moment was ccw or cw, especially for horizontal components but as soon as you showed the tip of drawing the line of action and recommended moving the force closer to the point of rotation, I had my "aha" moment.
2 minutes into the vid, I learned more than our 2 hour lesson. Thanks!! Edit: I wanna cry! By the end of the video I really understood the concept of determining directions. This video is a blessing, thank you!
Watching this five years later....the magic has not lost its power..I understood in an instant..I can't thank you enough...may God bless you beyond measure.😊
I was actually stuck on this exact problem and couldn't figure out the direction of the moment. Happened to stumble upon this video. Great explanation. Thanks!
Thank you so much for this tips. It really helps me other than the right hand rule method (sometimes I got confuse with that). Thank you very much, Mr. Smith.
Thank you very much Mr. Smith, this is very helpful for me to determine the direction of the momen, sorry for my bad english.. but i just want you to know that this is very helpful.. thank you so much
Thank you so much Sir. I was stuck on the exact confusion about a min before I bumped into this. Now I'm wondering if you can do one problem that has an unknown force.
Even though sir I am in 11th grade, it is a helpful video for me as nothing is given related to determining direction of moment produced in my physics textbook.
Thank you very much for the video it is very helpful .I would really love to know the author of that book it looks pretty equipped with nice questions for practice
Thank you sir. Although I have a question. You said to leave the negative or positive direction later after you got the sum of moments but wouldn't the direction affect the answer? If one component has a negative moment then it would be subtracted instead of added with the other component?
Are force sign standard + up and + right - down and - left. Moment sign of rotation can be assumed? Clockwise + counter - or clockwise - counter clockwise +?
