hey Chad from the bottom of my heart thank you, I'm planning on using you for my MCAT prep. Whether you know it or not you've been with me my whole premed journey and I'm really thankful such high quality content is available.

Hello! Why do we not include the normal forces for each person in the first problem?

At 24:46, why is the tension positive and the other torques negative? Why do we not consider clockwise and counter-clockwise rotation? Thanks!

A bit late, but he explained that CCW is positive because it is moving in an upwards direction. Clockwise, is down, or would be negative.

Hey, not to get too picky, but when solving for tension in the 2 dimensional problem, did you forget to divide by (sin30)(2.0m) when solving for T?

No, Sin(30) x 2m = 1m, so he just simplified it. He just didn't bother writing down the 1m as it was implied

Chad where u make video on cavity problem in centre of mass??

For the first example of the see-saw, you wrote out all of the forces but wouldnt there be normal force acting on the children sitting on the seesaw?
@ChadsPrep
@ChadsPrep Ай бұрын
These would be considered 'internal forces' which do not contribute to the torque - they are acting on the children in response to their contact force on the see-saw... it might help you to understand this by considering that when we are calculating torque here the children + see-saw is considered a whole unit

Hi chad, I don't understand the part where you choose the axis- of rotation. why for instance, the mass and Fn of seesaw neglected when you chose that area as the axis of rotation?
@ChadsPrep
@ChadsPrep Жыл бұрын
Hey Priyanshu, as I mentioned in the video I choose the pivot point in the center as the axis of rotation because we don't know the mass of the seesaw, but at that point (if there were no additional weights on the seesaw) the torque clockwise due to the seesaw is balanced by the counterclockwise torque, as the pivot point is in the center of the seesaw, similarly at this point Fn balances the weight of the seesaw. So by choosing the center where those unknown quantities cancel out to zero it makes life much easier for the calculation

The tension is 784N, you forgot divide sin30 on both sides. Good video tho.

sin (30 deg) is 1/2 and times 2 is 1 so he removes those terms and just subtracts the other group of terms. Even if he did not do the shortcut the sin30 is multiplied by 2 so you forgot to divide by 2
