Question

please ask that you clearly go over what is different in each spot (top, bottom, and middle? I don't understand the difference between the top and bottom, isnt there just a normal force up and gravity down for both ? And isnt there just a normal force up and gravity down in the middle too ?? Please help. And please make the force diagrams just so I can really understand. (and please, please solve the whole problem I really need to make sure I understand, I've gone to office hours and everything, this is over my head, please it would help me so much) Everytime someone answers they either dont do the whole problem or they do it but solve the whole thing in like three lines and I cant figure out. Please, I have posted this question four or five times but Ive run out of questions and Ive been paying three dollars to keep posting. thank you so much for your help.

5. A carnival ride consists of a vertical wheel of radius r rotating at angular velocity w around a horizontal axis. There is a horizontal platform attached to it; a person stands on the platform. (This platform stays horizontal, and does not rotate; the person remains upright during the whole ride.) This person has mass m, and stands orn a scale. The coefficient of static friction between their feet and the scale is 118-0.5. (a) Draw force diagrams for the person at the top of the circle, the bottom of the circle, and the position at the same height as the middle of the circle. (You will (b) How does the scale reading relate to the forces that act on the person standing (c) In terms of m, g, T, Hs, and w, what is the scale reading at the top?

(Hint: It's not any of the three positions marked.) erson will slide off of the platform. At what location will the person slide off?

Answer 1

We will draw fbd.
