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.
Q:What is the definition of lifting, slewing and luffing of tower cranes?
Rotary is cantilever tower crane tower crane rotary shaft winding;Is the hook shaft distance amplitude change;
Q:Are crane flies (the flying variety of the creature known as daddy long legs) actually poisonous?
The same program showed that the fangs were too small to puncture human or other mammals' skins. They have the poison, but can't deliver it to bigger creatures, sort of like North Korea.
Q:a question about ichabod crane? ten points!?
He was tall, but exceedingly lank, with narrow shoulders, long arms and legs, hands that dangled a mile out of his sleeves, feet that might have served for shovels, and his whole frame most loosely hung together. His head was small, and flat at top, with huge ears, large green glassy eyes, and a long snipe nose, so that it looked like a weather-cock, perched upon his spindle neck, to tell which way the wind blew. A rather tall, slender man with bad posture, and a large nose.
Q:When installing crane gold 1.6 roller rockers on an lt1, do you use any of the original rockers?
on the LT1 they come factory with screw in studs so the crane application should go without any problems the rocker the rocker guide from crane should slide right on to stud you don't use the old rocker guide for that
Q:Tower crane four limit, two insurance, two insurance what is that?
Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
Q:I have over 300 stuffed animals I've won from crane machines.....?
Wait! This is your fortune and your future! Was this not how you planned to retire one day? Consider your old age! :) Now that you're done laughing, call a children's charity. If they don't want them, donate them to the Salvation Army.
Q:I have so many crane flies this spring. Why?
cranes leave their habitat because the first reason was the climate , second its mating season and lastly scarcity of food in their habitat during winter .
Q:Why did they kill Secana Crane in the end of Hunger Games?
He angered the President by failing to stop the contestants from beating the game, so his death was demanded.
Q:i have to make a children's story about how the whooping crane became endangered; (based on real facts) ideas?
You could write a story about an old Whooping Crane with lots of children that goes on migration only to come back and find her home has been destroyed. So she goes and starts trying to raise awareness about it, and eventually finds a new home due to her efforts. This would need much more tweaking and changing of course.
