Q:I am 15 years old and into urban exploration. The only thing I haven t done yet is climb a crane. I don t want a big lecture on the dangers because I am fully aware of how dangerous it is and am also fully confident in my abilities. I am also ready to take full responsibility if I were caught. Although I know its Illegal, I don t know how Illegal it is and I would like to know the following...1. Will Crane Climbing get me charged with criminal trespassing?2. Will I get time in Juvenile?3. Is it possible that I could accidentally activate/deactivate something that would endanger the workers?4. What would happen if a worker got ahold of me?And again I feel like I need to mention that I don t want a Bull **** lecture on it not being safe. :): Yea, BS you'll be taking full responsibility. If you get hurt during this, who will have to take care of you? A parent. If you have to go to court, who is going to have to take time out of their day to go with you? A parent. Legal issues always have fines and court costs attached to them. Who is going to pay for that? Again- a parent.

Q:Equipment safety of tower crane: Safe distance tower and transmission line is not up to the requirements of the tower frame door frame to design, erection principle to power erection, do not use metal materials, bamboo and other materials can be used. The distance between a bamboo pole and a power line shall not be less than 1m, and a certain degree of stability shall be taken to prevent the wind from blowing. The tower crane height and bottom bearing size ratio is large, and the center of gravity of the tower body, high torque, braking frequency, impact force, in order to increase its stability, we will analysis the main causes of the tilting of the tower crane has the following:Overloading. Different types of cranes usually adopts the lifting torque based control, when the amplitude exceeds the rated load weight increase or the corresponding weights, the overturning moment more than stable moment of it, it may cause the collapse of the tower crane.Two, inclined hanging. Slant weights will increase its overturning moment, the lifting point will produce horizontal force and vertical force on the crane, bottom supporting point will produce an additional overturning moment, and the stability coefficient is reduced, resulting in tower crane collapse.Three, the tower crane foundation is uneven, the ground endurance is insufficient, the perpendicularity error is too big, also can cause the tower crane to overturn the moment to increase, causes the tower crane stability to reduce. Therefore, we should proceed from these key factors to strictly check, check and check, and prevent major equipment personal safety accidents. State explicitly eliminated the model should resolutely prohibit the use of, in disrepair, tower crane in the identification of the repair, to limit the use of load, tower crane for the use of fixed number of years there is no uniform standards, opinions vary, different places have different provisions.

Q:if anyone can inform me about any of these styles in debt even if just one id greatly appreciat itbest ansewer will be hard here cause i will b thankful for all who give a sincere ansewer: To be honest I wish I knew more, but here's what I do know of Wah Lum. They have great hand trapping techniques that can be utilized while standing. A perfect compliment for close quarter combat. They come in real handy in bridging the gap. They ( like Wing Chun ) have sensitivity drills used for heightening your awareness of your opponents subtle movements. If you're a boxer,wrestler,or basically any other Martial Art practitioner. This is a good Art to at least be acquainted with.

Q:He looked so out of his comfort zone at UFC 140. No support from either Silva or Seagal. Which brings me to another question. Why weren't those 2 by his side? Seagal or Silva are always at his side.Jones' height shouldn't be an issue. He should've at least tried to use it.: He did. Didn't you watch the fight? Here: youtu.be/3awhIoL54fY

Q:The arm of a crane at a construction site is 12.1 m long, and it makes an angle of 30° with the horizontal. Assume that the maximum load the crane can handle is limited by the amount of torque the load produces at the base of the arm. (a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N?(b) What is the maximum load for this crane at an angle of 35° with the horizontal?: (a) What is the magnitude of the maximum torque the crane can withstand if the maximum load the crane can handle is 500 N? τ = FL τ = 500(12.1cos30) τ = 5239.45 τ = 5240 Ν?m (b) What is the maximum load for this crane at an angle of 35° with the horizontal? τ = FL F = τ / L F = 5239.45 / 12.1cos35 F = 528.6109... F = 529 N I hope this helped. Please remember to vote a Best Answer from among your results. It's good karma as it keeps things in balanced exchange.

Q:↑ pretty much explains itself. (:~Animal_Lover: well maybe. depends on the type of paper crane. but i can make my own.

Q:Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?: Use trigonometry, it's a triangle of forces.

Q:As a building gets taller, the crane is raised. How is this done? And when the building is done, how do they get the crane back down?: they use a process called jumping. iron workers use a special fixture to unbolt the tower and lift the crane up high enough to slide in another section and bolt it down. breaking down of the crane goes in reverse order.

Q:I just can't figure this out. They need a crane to assemble tall buildings, but how do they assemble the crane? Especially if the building is over 20 stories high. What crane can build a crane higher than itself?: a mobile crane sets the original lower sections in place, and then the crane is assembled in 6' sections as it climbs itself.

Q:type of dc motors used by electric train/subway,crane & fan.give a brief explanation to your answer?: I believe that electric trains and subways use series motors when DC motors are used because the series motor has a torque vs. speed curve that provides high torque at low speed and low torque at high speed. Since power is equal to torque times speed, that is essentially a constant power mode of operation. I believe that mode is selected because it results in a smaller and less expensive complement of power delivery equipment and more efficient operation. Although it has been many years since DC motors were used extensively for cranes, I believe that series motors were used more than other types for the same reasons stated above. However, compound or separately excited motors may have been used for better speed and torque control at low speeds. Except for heater fans in vehicles, I don't believe DC motors have ever been used much for fans. Today, permanent magnet DC motors are used for all of the little motors in vehicles including the radiator fan that was formerly belt driven by the engine. A permanent magnet motor is like a separately excited motor or a shunt motor. The optimum DC motor for a fan would probably be a shunt motor because a fan requires increasing torque as speed increases. Today, computers are cooled by brushless DC motors.
