s/ttyme/OneDrive%20-%20Select%20Education%20Group/ch03%20(1).pdfAIn a popular amusement park ride, people stand on a circular platform which sits inside avertical cylinder. As the cylinder and platform spin about a vertical axis, the riders feel as ifthey are pushed against the inside wall of the cylinder. Once the rotation rate becomessufficiently high, the "floor" of the ride drops, leaving those inside effectively pinned to thewall. Draw force diagrams for the following cases. Is your force diagram consistent with therequirements for circular motion? Justify your answer.(a) The platform and the cylinder are spinning slowly. The people inside are standing on thefloor.

Given:The ride spins such that those inside get pinned to the inner walls of the ride.Asked:To draw force diagram or free body diagram (FBD) of the conditionwhen ride spins slowly, and people are still standinf on the floor.Also to justify whether theFBD is consistent with the requirements circular motion.Let R be the raduis of the cylinder,and the person be standing really close to the walls so its at R distance from center of the cylinder.Mass of the person be m.Angular velocity of the cylinder at that instance be ω.Now we see that the FBD shown above is completely in consistencewith the circular motion, as a centrifugal force is depicted in it.Centrifugal force Fcf = mω2r since for circular motion ω = vrFcf = mv2rAlso since the ride is spinning slowly,the weight mg of the personis acting on the floor, which produces a normal force NDue to the centrifugal force there is some force that the person produces on the inner walls of he cylinder and the walls produce normal force N' = mv2r and therefore the person is in equillibrium.Now when the ride spins such that people inside are pinned to inner walls and the floor drops, the weight still acts downwards and there is no N as there is no floow below the person.But since the inner wall will have some friction, there will be a frictional force opposing the weight of the person( acting upwards) f = mgwhich keeps the person pinned to the wall

A circular space station with a radius of 72 m has just been completed. In order to provide astronauts with the feeling of gravity, the space station will be set spinning about its central axis. To do this, solid fuel rockets have been attached around the perimeter of this station to start it spinning. These rockets fizzle out quickly, and produce a non-uniform angular acceleration of =a0e−bt Where a0 = 0.0424 rad/s2 and b = 0.153 s-1. The station is at rest (is not spinning) when the rockets are ignited at t = 0 s. What is the tangential speed of the outer edge of the station about the center of the station at t = 6.27 s? Through what angle has the station rotated in that time? Once the rockets are done burning, how long does it take the station to complete one revolution?

Artificial gravity is a must for any space station if humans are to live there for any extended length of time. Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside of the outer edge of the cylinder, which has a diameter of ?=2735 m that is large enough such that its curvature is not readily noticeable to the inhabitants. (The space station in the figure is not drawn to scale.) Once the space station is rotating at the necessary angular speed ? to create an artificial gravity of 1 g, how many minutes would it take the space station to make one revolution?
