- 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 is YOUR take on Louis Crane's idea of meduso-anthropic principle?
- Well Im not into quantum physics much these days, but in his book Life and Light Lee Smolin proposes that if the quantum theory of gravity has two special features the universe would fine tune itself! If we perturb a Kerr-Newmann black hole so that the new universe will really form on the other side, and that the constants of nature might fluctuate in such a process so that the new universe would have sightly different physics than our own. Its well over my head at this stage; cause Im just an N.Y.U.K. graduate! NYUK NYUK NYUK Anyone wants to read up on it can go to the link below.
- Q: would a tower crane be a first class, second class, or third class?
- The crane is balanced, with a fulcum somewhere between the ends. On one end, you have counter weight sometimes can be moved. On the end, you usually have the crane part, which can be trolleyed from the end toward the fulcum. If my memory serves me. a wheel barrow is a type 2, because the fulcum is on the end and the load is toward the middle. So this leaves you with a type 1 or 3. Try searching using the key word group lever type fulcum and I'll bet you get your answer.
- Q: Under what circumstances does a tower crane require third party testing?
- New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
- Q: The truck has a Comprehensive Motor insurance cover. There is no exclusion in the policy in respect of tools of trade.
- read your insurance policy.
- Q: Okay Answers community, I need your help. I recently received a thousand paper cranes for my birthday and I want to know, what's the best way to hang them up (like on fishing line etc.)? Also, at the moment I think I'd like to hang them up in my bedroom, in interesting patterns. Any suggestions for how to arrange the cranes, or other ideas for what to do with a thousand paper cranes? Just remember, I'd like to keep the lot!
- use all of them to create one big one (assuming they're all similar)
- Q: How to improve tower crane industry in china?
- Powerful okorder ) manufacturing standards according to the rules of tower crane industry market economy. ?? Manufacturing industry is a huge system, the formation of a broad face, not one or two companies can do a good job.

- Q: The question is: A crane has a power of 500watts, and is pulling a 142kg. What is the velocity of the pulling of the crane?Please help and thanks!
- I don't remember ever doing a problem like this, but I will try to solve it. P = W/Δt, P = Fd/Δt P = Fv Force required to lift the 142 kg object; F = 142 * 9.8 F = 1391.6 N Therefore; P = Fv 500 = 1391.6*v v = 0.359 m/s So velocity of the crane is 0.359 m/s. Is that right?
- Q: We see lots of cranes doing some heavy lifting during construction. But how do they get so high up these buildings? And when construction is nearly done, how do they go back down?
- Those type of cranes have a support system that is continuously built as the building gets taller. The crane climbs up on the support system to reach the next level and climbs down to get down
