- Q: Crane lifts a 600-kg bin with an initial acceleration of 2 m/s^2. Determine the force in each of the supporting cables due to this motion.?
- F = ma Assume the crate is uniformly loaded, both cables will carry the same force F(AB)(4/5) = (600/2)(9.8 + 2) F(AB)(4/5) = 3540 F(AB) = 4425 N F(BC) = 4425 N F(B-Crane) = 600(9.8 + 2) F(B-Crane) = 7080 N As a form of exchange, please remember to vote a Best Answer from among your results. This is not the same as like or thumbs up which are also nice and do boost points, but only after asker awards initial points with their vote.
- Q: Hey,My grandma has a big country estate with a river and its her birthday coming up. She's indicated she might like another peacock (we've had them before), but I'm thinking of branching out into other birds. We tried Lady Amerhursts pheasants, but one of the dogs knocked over their cage before they were properly acclimatised and they disappeared.So, does anyone know if its possible to get storks or cranes or other big waterbirds to keep as domestics?They'd be free ranging on the estate and the river, so need to be smart about foxes and mink (ie roost in trees or go into a house). We've kept geese and ducks successfully on our river like this, so does anyone have any ideas?Or should we try again with pretty pheasants?
- Depends on where you live ? Stick to Ornamental Pheasants or Ducks,Storks and Cranes,need to be penned in at night because you will have to pinion them to prevent them flying. Try some Golden Pheasants for a try ,Lady Amherst are becoming a rare commodity and are quite expensive,if you have Foxes and Mink,then no matter what you get you will have problems these two predators.
- Q: What does "jack up" tower crane 1000KNm mean?
- 1000KNm means that the rated lifting moment of the tower crane is 1000KNm. That is to say, the 100tm tower crane.
- Q: If any of you have read The Red Badge of courage by Stephen Crane can you please tell me what you think about it. Is it a good book or is it not?!!!! Do you praise it or critize it !? i need your opinion what's your review! Thanks

- Q: How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
- 2 the tower crane without counterweight is mainly the city fast loading tower crane. It is characterized by the absence of balance arm, and it is impossible to have counterweightThe layman can not tell the can see the appearance, there are long steel structure before and after the weight of the tower body, and no weight of the tower body with only one steel structure (i.e. jib crane, structure)
- Q: do they start with the crane house and keep adding sections underneath it? Or do they build they tower and then somehow top it with the actual crane?
- How Do They Grow? Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on a 40-foot (12-m) mast that consists of two mast sections. The mobile crane then adds the counterweights. The mast rises from this firm foundation. The mast is a large, triangulated lattice structure, typically 10 feet (3.2 meters) square. The triangulated structure gives the mast the strength to remain upright. To rise to its maximum height, the crane grows itself one mast section at a time! The crew uses a top climber or climbing frame that fits between the slewing unit and the top of the mast. Here's the process: The crew hangs a weight on the jib to balance the counterweight. The crew detaches the slewing unit from the top of the mast. Large hydraulic rams in the top climber push the slewing unit up 20 feet (6 m). The crane operator uses the crane to lift another 20-foot mast section into the gap opened by the climbing frame. Once bolted in place, the crane is 20 feet taller! Once the building is finished and it is time for the crane to come down, the process is reversed -- the crane disassembles its own mast and then smaller cranes disassemble the rest.
- Q: Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace for cooking? e.g. like in dutch ovens or pots/cauldrons that hang over a fire. It sounds like a more modern term and I need to know if there is an older term. Thanks.
- An older term might be randle bar, but I think both terms are fine to use.
- Q: The machine weight is 17500 KgEach crane capacity is 12500 KgThe lenght of beam is 4.5m and square cross section areaMaterial of beam is ASTM A 615 Gr60Machin connect to beam in 3 pointWhat is the beam cross section area dimension?
- You left out crucial information and working it out with risky assumptions takes too much work. Whatever this was supposed to mean Machin connect to beam in 3 point What is missing is whether the cranes connect to the end and the entire weight of the machine is in the middle - or is the machine attached at 3 distributed points. In addition, there has to be some condition - looking at the ASTM spec will give strength, but you have specified whether the beam is to be just at failure or 50% safety factor, etc.
- Q: Firstly, I realize that the 1000 paper crane thing is based on faith and not science. I'm not stupid. Secondly, Do the 1000 cranes have to be in the same place? If I send one of my cranes to a friend across the country, would that no longer count as part of my 1000 cranes?If a crane gets destroyed, must I start over or replace that crane?If anyone has any knowledge or link pertaining to the 1000 paper crane myth, please post it. Thank you.
- The myth seems to surround the FOLDING on the 1,000 cranes - it is the sacrifice on the part of the person doing the folding that is the magic not the cranes themselves. See the Wiki......
