Was able to solve a question I was stuck on for like 10+ minutes in less than 30 seconds after watching the first minute of this video. I think the key thing that most people don't realize is that, for boards of uniform density, the COM will be exactly in between (I didn't know that until watching this video!). If I knew that, life would be so much easier. Thank you so much for your help!

It's a weed out exam that's used to bais the applicant pool and make it easier with people from higher socioeconomic backgrounds of getting in becsuse they have the resources to pay for tutors etc to help them score better. Nothing new the medical field is full of biases just as any other discipline

That moment when you realize the 10 meter board was actually a given and the 10 was super washed out and it wasn't just called M-board after all.

Thank you!!! I never got to learn this in college even though I got the requisite grade because I had a terrible health problem that semester. Three years later, I finally understand what my professor meant by saying that we could choose the point of rotation. Now I just have to go do a bunch of practice problems!

@dasraththakkar81374 жыл бұрын
if we take the axis of rotation above the 10 kg object then the problem would be way more simpler ?because the torque about it will be zero

Are "weight" and "mass" interchangeable terms on the MCAT? To my mind, when the question asks how "heavy" an objects is, I would assume it is asking for the "weight" (mass x accel. due to grav.), which would be (15kg x 10m/s^2)=150. Thanks for all the great vids.

Anyone know what the m.10 stands for under the 10m board. Thanks
@AtomsAndStories2 жыл бұрын
Hi! I'm a Senior High School Physics teacher. This might be late but just to answer, the "m10" represents the WEIGHT of the board - one of the downward forces acting on the system aside from the hanging 10-kg mass at the end. To explain why "m10" is the weight of the board: By definition, Weight = mass x gravitational acceleration Since mass is unknown, he retained it as "m", but gravitational acceleration is 9.8 m/s/s in terms of magnitude, and some references actually use "10" instead of 9.8 for simplicity. So yeah, "m10" is the "mass x gravitational acceleration" also known as the weight (of the board).

@ThePigMange5 жыл бұрын
The distance for your counter clockwise point from the center of mass isn't arbitrary, so I don't see how it can be used to calculate the mass of the board. For example, if I set the d to 1, then m=30kg, to 3m, then m is 10kg.

If the board is 8m long than the Fg will be?
@zZFuRiouSZz5 жыл бұрын
Your lever arm would then become 1m on the left and thus Fg would be m which you would calculate to be 30N I believe. Sorry for answering so late.

if the board has a mass, than it will also account the torque in clockwise as well. that is not considered in your equation.

@khushaliroy66126 жыл бұрын
the center of mass is to the left of the point of rotation. the torque is ccw, not cw.
