Re: Biochem Video's in Lesson 13

Thanks Brian,

Yes, I am using Firefox. Wow, I didn't even know that was there. Thank you, I will submit the tech ticket.

Sincerely,

Biochem Video's in Lesson 13

What is going on with these videos in lesson 13? The video and sound are not working for any of the videos. Can somebody fix this?

Thank you,

Re: Lesson 18, Physics Video 2

Could the line labeled as lowercase "Omega" (ω) mean the object distance from the Y axis, and the v= the image distance from the vertical axis?

Lesson 18, Physics Video 2

On Slide 9, there is an optics worksheet about Ray Diagrams. On the second row, below the axis of symmetry before the lens, there is a line drawn indicated as Omega. There is another line in front of the lens labeled V. What do these two symbols, omega and V mean? Also, could someone please respond ...

Re: Lesson 5 Video 3

Andrew,

Hope all is well. I'm sorry, I just realized a simple mistake that I made. The ankle is a class 2 lever not a class 1 lever, so the load is in the middle, not the fulcrum. I just wanted to correct for that. Every time I said fulcrum I meant to say load.

Sincerely,

Re: Lesson 5 Video 3

I'm sorry I think I have that last post backwards. But I think I understand the concept... please correct me if I'm wrong. Big picture: The system is in equilibrium. Torque of the toes on the ground must equal torque of the achilles tendon lifting the body. Is it safe to say that the torque of the t...

Re: Lesson 5 Video 3

And sense the radius of the lever arm from the fulcrum to the ground is 12cm, is the torque of the force on the lever arm from toes on the ground to the fulcrum = 2250N? And the torque of the achilles tendon, because the radius of the lever arm is 4cm or 0.04m, the torque of the achilles tendon is 9...

Lesson 5 Video 3

Just a quick question: In physics lesson 5 video 3 slide 5, Brian is talking about the force applied to the achilles tendon. Overall, from what I see of the ankle figure, the radius of the force from the fulcrum to the achilles tendon is 4cm. The radius of the force from the ground to the fulcrum is...

Lesson 5 Video 2

Last night during Office Hours we went over a physics question that I did not understand. I also found the question in Lesson 5 Video 2, Slide 4. After reviewing the video, I still did not understand. The question states: What is the mass of the brass weight hanging from the end of the string if the...
