Steel I beams
The "W" in steel I-beam designations refers to wide-flanged beams. Most wide-flanged beams are symmetric about both the vertical and horizontal axes.
Usually by bolting or welding them.

p1=power of 1st crane p2=power of 2nd crane p1= 2 p2 {But power = Velocity * Force weight of both steel is same so force is same for both p1=2p2 V1 * F=2( V2 * F) V1 = 2 V2 therfore velocity of 1st steel moving up is 2 times that of the 2nd steel bar moving up Or the cranes are set at different angles - bam2
Yes there are multiply size of crane trucks. You can go from ones that pick up cars to huge ones that can be tall eough to lift steel beams to the roofs of sky scrapers.

A crane hook is the hook used on an operating crane. These heavy hooks are usually comprised out of steel material.
Among our handy steel beam tables you can find standard beams' dimensions and beams' weights, steel hollow sections tables and other steel profiles data.

You can purchase steel beams from anywhere from Home Depot to Global Industrial. Global Industrial is the number 1 location for this type of material.
They are called Side Impact Door Beams. They can be made of steel, aluminum, or carbon fiber.
In the car analogy for cells, the cytoskeleton would be the steel framework. The cytoskeleton supports the cell like the steel framework supports the car.
A rivet gun is used to punch steel bolts into steel beams.
crane hook is made of quenched & tempered alloy steel.
A scrap crane is a crane (mobile or EOT -electric overhead traveling) in a scrap yard most commonly steel scrap. The applicaton I use is a EOT crane with a magnet. It loads steel scrap into a ladle which goes into a electric arc furnace.
