Q:What is the service life of the mobile scaffolding accessories?

The overall life of cold galvanized mobile scaffolding accessories for about 5 years, the surface does not require maintenance, moderate cost. The main processing technology: the welding of the scaffolding parts and then galvanized, the surface of each part, are galvanized. 5 years of surface treatment period, and the use of the elimination period, very close to the larger share of the market share.

Q:Want to rent the scaffolding in the county, you need to cast how much money

In addition, there are disc scaffolding and other accessories, so you can estimate how much you need to invest

Q:He pushes a can over the scaffold at 15 meters and it takes 3.25 seconds for it to land.I keep doing the problem over and over. the Correct answer is 20.5 m/s, however I keep arriving to the solution of 17 m/s. I solved it by doing Vf^2 = Vi^2 + 2adwhere the initial velocity is zero and the acceleration is -g. I made my coordinate system so that down is negative in which the distance will be negative. This however, did not give me the correct answer. Am I right or is the book right?

The initial velocity is not zero since the scaffold is moving upward when the can gets pushed over. And final velocity, vf, does not represent the speed of the scaffold (if that is what you're trying to solve). y = (vo)(t) - (1/2)gt? 15 m = (vo)(3.25 s) - (1/2)(9.81 m/s?)(3.25 s)? vo = +20.5 m/s

Q:What are the requirements for the construction of the scaffold eye in the building?

The surface of the steel pipe shall be smooth and free of cracks, scars, delamination, dislocation, hard bending, burrs, indentation and deep scratches.The outer diameter of steel pipe 48mm allowable deviation is 0.5mm; the thickness of the wall 3.5mm allowable deviation of.0.5mm; steel pipe surface cutting oblique deviation 1.7mm;

Q:What are the chances of cracking the tile? What can I do to avoid cracking the tile?This will be 3 levels of scaffolding on 6 inch wheels.

unless you are majorly manhandling the scaffolding, such as slamming it around and jerking it into place, etc, you won't crack the tiles (this is being said with the hopes that the flooring was installed correctly.) i would throw a layer or two of bedsheets or a good heavy drop cloth over the tiled floor just to protect the tile from being chipped or scratched. be careful going up so high. good luck!

Q:The basic form of external scaffolding

The bowl buckle steel tube scaffold is composed of steel pipe pole, cross bar, bowl buckle joint and so on. The basic structure and erection requirements and fastener type steel pipe scaffolding similar, the main difference lies in the bowl buckle joint.The bowl buckle joint is the core component of the scaffold system, which consists of the upper bowl buckle, the lower bowl buckle, the cross bar joint and the limit pin on the upper bowl buckle.

Q:Are the terms quot;nuclear matrixquot; and quot;nuclear scaffoldquot; interchangeable? I know that when we talk about DNA compaction we say that MARs on the DNA attach to the nuclear scaffold. I am wondering if the scaffold is just a specific part of the matrix??

For most purposes, they are interchangeable terms for the same things. Some people favor one term, some the other. The ones who favor matrix over scaffold or vice versa may have some argument as to why it is better or a difference but in general people use them interchangeably.

Q:I want to know the classification of scaffolding in the building

Steel pipe scaffold. The utility model is composed of two or more steel pipes of different specifications, such as a door type scaffold.

Q:I had my scaffold pierced yesterday and now it is swollen and red. Its throbbing and painful. I have cleaned it and applied ice and antiseptic spray.I don't own any sea salt.HELP ME! I'M SO TEMPTED TO REMOVE IT.

Antiseptics are too harsh for a healing piercing, the pain, swelling and redness is completely normal. Stop using antiseptic and go to the grocery store to get some non-iodized sea salt, its only a few dollars and you can find it in the spice aisle where the regular salt is.
