Q: The bottom of the cantilever scaffold must be provided with the sweeping rod: The quality standard of the foot hand frame fittings: 1, steel pipe: (1) the steel pipe adopts the outside diameter is 48mm, the wall thickness is 3.5mm, the quality standard of the foot hand frame fittings

Q: I'm trying to understand a problem in my physics book. The problem is this:A person is pulling on a rope, that is connected to a pulley on the ceiling. The rope then goes to a box with a pulley on it, and then up to the ceiling where the rope is connected (to the ceiling).The rope and pulleys are massless and frictionless.The book lists three forces (tension forces) going up and one weight force pulling down.My question is, why isn't there another force pulling against the tension of the rope from the guy pulling the rope?: The force felt by the person pulling is the same as the force in the rope between the two pulleys. It doesn't matter if the person is pulling straight up (without the pulley) or straight down(with the pulley) it's the same. Therefore the weight/force is divided equally between the two ropes.

Q: Every time someone in medieval times was murdered by the beheading a new scaffold was built for the next prisoner.: Well that's not entirely true; they didn't ALWAYS built a new scaffold. Probably movies let you think so but that was not the case.

Q: Scaffolding installation process, construction preparation: Construction preparation(1): steel pipe should be consistent with current national standard "carbon structural steel" (GB/T700) regulations Q235- grade steel; new steel pipe should be the product quality certificate; steel surface should be flat and smooth, no cracks, scarring, delamination, dislocation, bend, burr, indentation and scratch depth, pipe diameter deviation not more than -0.5mm, the wall thickness deviation not greater than -0.5mm, cutting slope deviation not greater than 1.7mm, the steel surface should be brushed with antirust paint; old steel corrosion depth not greater than 0.5mm, more than the prescribed steel shall not be used.(2): buckle made of malleable iron fasteners, the material should be consistent with current national standard "steel pipe scaffolding fasteners" (GB15831) regulations; old buckle inspect before use, shall not have cracks, deformation, bolt appear smooth silk must be replaced; new and old fastener must brush good antirust paint.(3) foot board: the use of 4m long wooden foot board; foot width of not less than 200mm, the thickness is not less than 50mm, both ends should be set with a diameter of 4mm galvanized steel hoop two; rotten feet can not be used.(4) safety net, paint.(5) after the inspection and acceptance of the above parts have been classified and piled up in a neat and orderly manner, no water can be accumulated.2, scaffolding erection and removal(1) scaffold erection

Q: I am currently taking early childhood care education as my college major. I am learning about ZPD (Zone of Proximal Development), and scaffolding the the development in early childhood.How would you explain, and define scaffolding: Maybe this will help: scaffolding is the support provided by adults working with a child to help promote and extend development of knowledge and skills. It can mean asking appropriate questions to help extend a child's thought process, or providing suitable activities to help a child learn through hands-on activities. Look it up in your textbook and read the definition and apply it to my explanation above for a deeper understanding, and don't be afraid to ask your instructor questions like this! That's what s/he is there for!

Q: For indoor use of mobile scaffolding safety construction plan! Four support points with four pulleys with brake!The construction scheme of scaffolding safety belt for indoor high Jiqiu braking pulley, for about 12 meters of buildings, indoor emergency please heroes!: Wall point setWhen the height is not less than 6.0m, you must set the uniform distribution of wall, its setting should meet the following requirements:Door type steel pipe scaffold: when height is less than or equal to 20m, less than 50m2 of a wall, and even the vertical spacing wall point should be less than or equal to 6m; when the frame of high >20m, not less than 30 M2 a point, and even the vertical spacing wall point should be less than 4m.The other floor (or bottom bracket) scaffolding frame: when high than 20m, a point of not less than 40m2, and even the vertical spacing wall point should be less than or equal to 6m; when the high frame >20m, a point of not less than 30m2, and even the vertical spacing wall point should be less than 4m.The free height of the upper wall of the scaffold is not more than 6m.

Q: Bowl buckle type steel pipe scaffolding should set up a few people: What are the form and structure of bowl buckle scaffold?Composition formA bowl type steel tube scaffold is a multifunctional scaffold in our country with reference to foreign experience developed, its member nodes connected with bowl, because the bowl is fixed on the steel pipe, all components of the axial connection, good mechanical properties, which is reliable, consisting of the scaffold with good integrity, there is no fastener lost problem.

Q: Can anybody provide me the formula for calculating scaffold volume on circular tank?: Step 1. Measure the diameter of the tank (D). Step 2. Measure the height (h) for a vertical tank or length (l) of a horizontal tank. Step 3. Calculate the cross-sectional area of the tank using Equation 1. Equation 1: Cross-sectional Area, A = 3.14 x D x D/4 Step 4. Calculate the volume of the tank in cubic feet using Equation 2. Equation 2: Volume in cubic feet = A x h [for a vertical tank] Volume in cubic feet = A x l [for a horizontal tank] Step 5. Convert the volume of the tank from cubic feet to gallons using Equation 3. Equation 3: Volume in gallons = (Volume in cubic feet) x 7.48

Q: hi, ive had my scaffolding for a little over a month now, and one of the holes has started going really weird. on the top, its swollen and sore on one side, and on the bottom, its the same but on the opposite side. not sure if its infected ir being rejected by ear, which ive heard can happen. i would like to keep it in if possible,as i love it. any help welcomed :) thanks xx: Normally if there is an infection it is very very sore, red, warm to the touch, and secretes yellow or green pus. It sounds like you might also be possibly forming a keloid, but most likely it is just irritated. Continue with your sea salt soaks (hopefully thats what your doing) and go down to your piercer and have them check it out if you get too worried about it.
