Question

All of t rod of mass B. 2a _x10 kg and length C. 5meters, with two identical uniform hollow spheres, each of mass D. 232x 10 kg a E_ meters, attached at the ends of the rod, as shown below. Note that none of the diagrams shown is drawn to scale! he questions on this exam concern a space station, consisting of a long thin uniform nd radius axis axis (e) Now, another feature of this station is that the rod-shaped section can change its length (kind of like an old-fashioned telescope), without changing its overall mass and remaining uniform in its density. Suppose that, however it was accomplished, the station is now rotating at a constant angular velocity of F rad/s.If the length of the rod is reduced to K. 2426 meters, what will be the new angular velocity of the space station? ans 90 degree perspective shit so you're looking straight along the new rotabion ais (d) Let's start again with the station not rotating, and back to its original size, with the rod again at meters long. This time, we would like to get the station rotating at a rate of IL rad/s, but now about an axis that passes straight down the length of the rod. We will accomplish this by placing a pair of rocket engines as shown, each again with a thrust of G, 4. order to get the station's angular velocity up to F· O·ㅛ rad/s? Answer:- minutes 4-x 106 N, on one of the spherical end modules. How long must these engines fire in
