- Q: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
- Q: What makes a crane so strong?
- Cranes are built using a structural technique called a truss which is characterized by looking like a series of triangles connected together. That structure prevents the members from having to resist any bending loads. All of the truss members experience only tension and compression, no bending. That is an extremely efficient structure which is why they can be so strong without being monstrously heavy. Or if you prefer the short answer, engineers make the crane so strong.
- Q: What do you do after you made 1000 paper cranes. I know you string them up, but storing them is hard. Do you ceremoniously burn them or what? When can they be gone? This is the missing link in the story I want to know. I have 846 and I want to know what to do after I'm done.
- i know this big organisation in Japan and some of my frineds live there... if you are interested, I can give you the address and more details...etc
- Q: I am doing uni coursework to design an ergonomic layout for an operator cab for a tower crane and so I need to list the required operator controls.Thanks!
- There are only two control levers that are on a tower crane.There is one on either side of the seat called joy sticks the right side joy stick controls the hoist cable to go up and down pushed forward to go down and pulled back to hoist up.The left has four functions it controls the swing of the crane and also the boom of the crane to control the swing you push the lever to the left to swing left and push the lever right to swing right.You pull the lever back to boom up and puh it forward to boom down.
- Q: I still cannot grasp how a crane was taken apart on a building with no roof
- They used a climbing crane , and who said that the building has no roof? the crane parts can be dismantled on site and removed either by helicopters or using the construction lifts
- Q: I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?
- First, okorder /. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.
- Q: I want to know how to make the best and easyist paper crane with origami.
- How okorder /
- Q: stories about paper cranes?
- Sadako and the Thousand Paper Cranes by Eleanor Coerr - about a girl who gets luekemia from the Atom bomb dropped on Hiroshima and her making paper cranes to pass the time in the hospital.
- Q: Form the movie Dreamer, daughter of Ben Crane
- It was Dakota Fanning that played Cale Crane, daughter of Ben Crane in the film Dreamer: Inspired by a True Story. She's a good little actress. I love to watch her films.
- Q: a/ Calculate the lift workb/ What is the power used by the crane when the efficiency is 60%? (Can you explain for me what efficiency means)c/ What will the kinetic energy of the load be when it hits the ground, if it falls from the height 8.5 meters, g=9.81 m/s^2Thank you.
- The work done (W)= Force*Distance. Force is 9.81*3000kg. So W = 9.81*3000*8.5 = 250,155 J Power (P)= Work(W)/Time(t) = 250,155/15 = 16,677 W 60% efficiency means that the lift is only using 60% of its maximum amount of power output. So to find 100% (lets call it x) of the crane's efficiency, consider the following: x * 0.6 = 16,677 x = 16,677 / 0.6 = 27,795 W Total mechanical energy in a system remains constant, so the kinetic energy the moment it hits the ground equals the potential energy when it is still hanging in the air. Potential energy = mgh = 3000x9.81x8.5 = 250,155 J You know this is correct, because it is the same amount of work the crane performed on the object to lift it.
