Question

You are planning on hanging the famous Wookie Lisa in a turbolift. The cables you have available can each support 120 N of tension. The painting's mass is 50 kg. In the event of an emergency, the turbolift is designed to brake at a rate of 3g g , where g g corresponds to Earth gravity. In order to avoid damage to the painting, you want to use enough cables so that no one cable exerts a force greater than 72 N on the painting. On the other hand, Chancellor Palpatine himself, citing the clone army budget, has demanded that you use the minimum number of cables. How many cables do you use?

Answer 1

Net Weight should be balaced by tension in the cable t= mg + 3mg = 4mg = ¢x 5019,8 T = 1960N since I cable exerta force of 720 Ano. of cables no 1960 required = 27,22 nr 28 cables
