Cool Find The Tension In An Elevator Cable 2022
Cool Find The Tension In An Elevator Cable 2022. Find the tension in the supporting cable when the cab, originally moving downward at 12 m/s,is brought to rest with constant acceleration in a distance of 42 m. Find the tension in the supporting cable when the elevator, originally moving downward at 11 m/s, is brought to rest with constant acceleration in a distance of 43 m.
First take the case when elevator is moving upward: So, the formula for tension: The cable tension and gravity.
An Elevator Weighing 2,000 Lb Attains An Upward Velocity Of 16 Fps In 4 Seconds With Uniform Acceleration.
Find the reading r of the scale in newtons during this interval and the upward velocity v of the elevator at the end of the 3 seconds. If the rope is at an angle from the level of the floor, we need to compute for the horizontal component of the pulling force too. The counterweights provide tension for the cables to hold the elevator.
The Total Mass Of The Elevator, Man, And Scale Is 750 Kg.
Find the tension tin the supporting cable when the elevator, originally moving downwards at 20 ms is brought to rest with constant retardation in a distance of 50 m. Let the tension in the cable = t 1 n. The weight of the elevator, m g = 4000 n.
In Essence, The Cable Is Providing An Upward Acceleration Of 9.8 M/S 2 To Balance Out The Downward Acceleration Of Gravity.
Gave me a value of.78seconds. Experts are tested by chegg as specialists in their subject area. The kinetic energy of the elevator as it reaches 10 meter is 10,000 joules.
Find The Tension In The Supporting Cable When The Cab, Originally Moving Downward At 12 M/S,Is Brought To Rest With Constant Acceleration In A Distance Of 42 M.
This works as long as the elevator and block move together. An elevator is a box that moves up and down a building with the help of strong cables. An elevator and its load have a combined mass of 1600 kg.
Mass Of Elevator = 1000 Kg.
The elevator is at rest the forces acting on the elevator can be represented by: So the tension in the string will be equal to the gravitational force mg. During the first 3 seconds of motion from rest, the tension t in the hoisting cable is 8300 n.
