A steel cable to be used in a suspension bridge (loaded in tension) must support a weight equivalent to 1500 kg. If the elastic limit of the steel to use is σy= 1380 MPa, y and the UTS = 1550 MPa, calculate: a) Minimum diameter of the cable to avoid failure. b) How this diameter must be modified if a security factor of 2.5 is used.

A mineshaft has an elevator hung from a single steel-wire cable of diameter 2.5 cm. Young's modulus of the cable is 10×1010N/m2. When the cable is fully extended, the end of the cable is 600 m below the support. How much does the fully extended cable stretch when 1000 kg of ore is loaded into the elevator?

A mineshaft has an elevator hung from a single steel-wire cable of diameter 2.5 cm. Young's modulus of the cable is 10×1010N/m2. When the cable is fully extended, the end of the cable is 900 m below the support. How much does the fully extended cable stretch when 1200 kg of ore is loaded into the elevator?

One kind of elevator has the elevator car hanging from a cable,
which then passes over a pulley and connects to a counterweight, as
shown in (Figure 1). The mass of a fully-loaded elevator (that is,
the elevator and all its passengers) is 1850 kg , the mass of the
counterweight is 1500 kg , and the pulley has a radius of 0.4 m
and a mass of 400 kg . A motor drives the motion of the elevator by...

4) [10 marks] A steel cable is being used to hoist a load of mass Mload 3.3 metric tons through a vertical height L. The steel cable has mass density p 7600kgm3 and tensile strength S-2.5 x 108 Pa. For safety reasons, the stress in the cable (that is the force per unit area) must not exceed Smax - 0.8S. In this question, the mass of the cable cannot be neglected . First assume that the cable has uniform cross-sectional...

A fully loaded, slow-moving freight elevator has a cab with a total mass of 1300 kg, which is required to travel upward 47 m in 3.5 min, starting and ending at rest. The elevator's counterweight has a mass of only 800 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?

A laboratory freight elevator,
including its load, has a mass of 500 kg. It is prevented from
rotating by the track and wheels mounted along its sides. The
elevator is used to carry highly sensitive equipment so it cannot
exceed an acceleration of 3 m/s2 . A geared motor is used with the
cable/pulley system shown below to raise and lower the elevator.
The motor turns gear A with a constant angular acceleration, αA.
The gears of the motor have...

A skyscraper in Manhattan has an elevator that weighs 1000 kg when loaded. The elevator is lifted at a constant rate to 480m above the ground by an electric winch motor. The drum of the winch motor is a solid uniform cylindrical drum in which a steel cable can wrap around it. The mass of the drum is 500 kg and has a diameter of 1 m. It takes the elevator a total of 120 s to get to the...
