Unformatted text preview: Discussion # Full Name: (11. You have been hired to design the interior of a special executive express elevator for a new office building. The elevator has all the latest safety features and will stop with an acceleration of QB in case of an emergency. The management wants a decorative lamp hanging from the unusually high ceiling of the elevator. You design a lamp which has three sections which hang one directly below the other. Each section is attached to the previous one by a single thin wire. The lamp is also attached to the ceiling by a single wire. Each section of the lamp weighs 7.0 N. Because the idea is to make each section appear that it is floating on air without support, you want to use the thinnest wire possible. Unfortunately the thinner the wire the weaker it is. To help you determine the thinnest wire that can be used for each stage of the lamp, calculate the tension force in each wire in case of an emergency stop.
