Q:IF YOU HAVE'T READ THIS BOOK, DON'T ANSWER! In Suzanne Collins novel, Catching Fire, who is Seneca Crane?
Seneca Crane is the previous Gamemaker who decided to allow Peeta and Katniss to live after the berry incident. The Capitol killed her and replaced her for that act of mercy. That's why Katniss hung her; she was rebelling against the Capitol and implying that they murdered Seneca Crane.
Q:What species depend on Siberian Cranes? What would happen if they become extinct?
No animals depend on Siberian crane but they are a source of food to carnivores in the wild.They are usually secondary source because there are mroe source of food that carnivores could eat.SO if they are extinct,it would not be a problem...its only destroying natures beauty!
Q:how do you string paper cranes together?
There should be a tiny hole at the bottom. Thread some colorful embroidery floss onto a needle, poke the needle through the hole in the bottom and straight up through the point at the top (on the crane's back). You can string one after another like this. You'll have to just take a guess on the length of the thread that you'll need, and be sure to knot it on the end. I have dozens of strings that I've made and given to friends like this. If you like, you can separate each crane by a colorful glass bead. It looks really cheerful.
Q:How's electricity delivered to Overhead Cranes?
Hot rails running along side the beams Hot shoes on the crane make contact with the hot rails and slide along the hot rails. Hot rails mounted to the beams by insulating bells. The hot rails can be anywhere in size from trolley wires to rails the size of railroad track rails. AC cranes are usually 3 phase so they will have 3 hot rails. DC cranes will usually have just 2 hot rails. Main disconnect/lock out feeds hot rails. It is usually fused but can also be just a disconnect switch. The same arrangement also is used on the crane's trolley. But in the case of the trolley one set of hot rails feeds the trolley motor. One set of hot rails feeds the main hook {big hook} motor: One set of hot rails feeds the auxiliary hook motor {little hook} motor. If the crane is also used as a Mag crane {Electro magnetic can be used} it will also have a set of hot rails going to the trolley for the magnetic

Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
The lightning resistance of tower crane (tower crane) on the construction site shall be no more than 4 ohms.I. tower crane GB/T 5031--20085.5.5.9 lightning protectionIn order to avoid lightning stroke, the main structure of the tower crane, the motor frame and all the electrical equipment metal shell, wire metal protection tube should be reliable grounding, and its grounding resistance should be no more than 4 ohms. When multiple repetitive earthing is adopted, the grounding resistance shall be no more than 10 ohms.Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms. Repeated earthing resistance is not greater than l0. The selection and installation of the earthing device shall comply with the relevant requirements of the electrical safety.The insulation resistance of the 8.1.7 main circuit and control circuit shall not be less than 0.5M ohm.
Q:I need help on finding the least amount of steps on how to make an oragami crane.?
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
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.
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.
