You are designing a high-speed elevator for a new skyscraper. The elevator will have a mass limit of 2400 kg (including passengers). For passenger comfort, you choose the maximum ascent speed to be 18.0 m/s, the maximum descent speed to be 10.0 m/s, and the maximum acceleration magnitude to be 2.70 m/s2. Ignore friction. A). What is the maximum upward force that the supporting cables exert on the elevator car? B). What is the minimum upward force that the supporting cables exert on the elevator car? C). What is the minimum time it will take the elevator to ascend from the lobby to the observation deck, a vertical displacement of 640 m? D).What is the maximum value of a 60.0-kg passenger’s apparent weight during the ascent? E). What is the minimum value of a 60.0-kg passenger’s apparent weight during the ascent? F). What is the minimum time it will take the elevator to descend to the lobby from the observation deck, a vertical displacement of 640 m?

You are an engineering consultant hired to verify an elevator design. The elevator mass is 500kg and has a maximum occupant capacity of 800kg. Carbon steel cables with total cross sectional area of 64cm2 support the elevator. The maximum speed of the elevator is 2 meters per second. At the maximum speed, each cable extends at least 4 meters and cannot extend more than 22 meters, unstretched. When the car is not moving and the cables are extended by 22...

In the worst-case scenario, you've got an elevator with a mass 2420 kg moving a speed 4.29 m/s when it reaches the bottom of the shaft. Your first idea is to put a spring, with spring constant 1.068×104 N/m, at the bottom of the shaft. a)Assuming the spring obeys Hooke's Law perfectly, how far will it compress to stop the elevator? b)When the elevator comes to a stop with the spring compressed, what is the net force on the elevator?...

You have been hired by a company that is designing a new slide (Chorrera) for an aquatic amusement park. In the conceptual design, a customer is expected to go down the curved end slide and then move horizontally across the bottom. At the end of the slide, the client grasps the end of a 16.0 m long vertical bar that can rotate around its center. After holding on to the bar, the client falls into a pool. When the bar...

An elevator packed with people has a mass of 1900 kg. The elevator accelerates upward (in the positive direction) from rest at a rate of 1.95 m/s2 for 2.4 s. Calculate the tension in the cable supporting the elevator in newtons. The elevator continues upward at constant velocity for 8.1 s. What is the tension in the cable, in Newtons, during this time? The elevator experiences a negative acceleration at a rate of 0.75 m/s2 for 2.8 s. What is...

You have been asked to design an elevator system. The functions of an elevator includes moving up and down, open and close doors, and pick up passengers. The elevator is supposed to be used in a building having floors numbered from 1 to MaxFloor, where the first floor is the lobby. There are car call buttons in the car corresponding to each floor. For every floor except for the top floor and the lobby, there are two hall call buttons...

A test automobile of mass 1350 kg moving at high speed crashes into a wall. The average temperature of the car is measured to rise by 0.6°C after the wreck. What is the change in mass of the car? (Assume the average specific heat of the automobile is close to that of steel, 0.11 cal·g·°C.) _______kg Where does this change in mass come from?

you are an analyst working for the new Joint High Speed Vessel (JHSV) program office. Several tests have been conducted on two different types of experimental test vessels (denoted simply “1” and “2”) to determine their performance characteristics under various loading and sea state conditions. With detailed data on the fuel consumption of vessel "1," and with the Navy's new focus on energy efficiency, the program manager wants to test whether the vessel beats the design specs in terms of...

You are in charge of designing a catapult that must launch a rock of mass m using a single spring that can only be compressed a distance x. The catapult’s target is located a distance L away from the catapult, but there is a wall of height L/3 located halfway between the catapult and the target. Determine the smallest spring constant (and the corresponding launch angle) that will allow you to hit the target. (You can make the simplifying assumption...

Suppose that you are working as part of a team designing a network for XYZ high school. Consider that the school has six departments, Admin, Academic, Human Resource (HR), Finance, IT support and Sports. 1. Analyse the project hardware requirements along with the number of devices and cost. 2. Justify the approach you would be taking to design the network for the school. 3. Using the network simulator (such as packet tracer) design the network. 4. Illustrate the network configuration...
