Q:A uniform 300nt. scaffold is 8 meters long. it hangs from two ropes, one at ech end. A 700nt painter stands...?
Let's mark left end as point A and right end as point B Let tensions in left and right rope are SA and SB respectively. Let G is weight of painter and Q is weight of scaffold. Let center of weight of painter is a=2m from A. Length of scaffold is L=8m Center of weight of scaffold is at its middle point b=L/2=8/2=4m from point A Two conditions of equilibrium: 1° there is no rotation ---> the sum of moments (torques) in any point of scaffold is zero. For point A: ΣMA = 0 (let's consider clockwise direction as positive) G*a + Q*b - SB*L = 0 ....(1) 2° there is no translation ---> the sum of all vertical forces including forces of tension in two ropes is zero ΣFy = 0 (let's consider downward direction as positive) G + Q - SA - SB = 0 .....(2) From (1) SB = (G*a + Q*b) / L SB = (700*2 + 300*4) / 8 = 325 N and from (2) SA = G + Q - SB SA = 700 + 300 - 325 = 675 N
Q:Bubble on industrial/scaffold piercing?
If the bump does not ooze any fluids and does not hurt, also has the color of your skin you know it's a hypertrophic scarring bump. Those bumps are formations of scar tissue ( new skin that is naturally created to heal a piercing ) and it goes away with proper care just takes time to do so. If the bump does ooze any fluids like blood or pus or whatever and it does hurt you know it's a cyst/boil. If this cyst is filled with yellow fluids or pus you know that it also got infected. Both of those bumps are treated with sea salt soaks twice a day. Soak the piercing in and do not just use a tissue. Warm water (8oz) + non iodized salt (1/4 teaspoon) mixed in a cup. Soak the piercing in for 10 minutes, 2 times a day. Use a q-tip to clean around the piercing thoroughly, rinse with water and pat it dry with a paper towel. Another alternative which helps for hypertrophic scarring bumps is the chamomile soaks. Industrial is a piercing that goes through cartilage and not just skin. It's not an easy piercing and healing time is 1 full year. Do not stop the sea salt soaks and do not get lazy because cartilage piercings have their ups and downs while healing. They can stay irritated, swollen and painful for long, bumps can be formed around them which can also get infected etc. All this goes away after proper care but can happen again days or even months later. So you need to be extra careful with those piercings and follow your piercers aftercare instructions by the book. Until the piercing is fully healed don't : Touch it, twist the jewelry, change the jewelry or take it out, sleep on it, play with it, but only touch it with freshly washed hands to clean it.
Q:Questions about Scaffold piercing?
It hurts like hell! Probably one of the most painful ones I've had. I don't know about taking it out as mine is still in but any piercing will leave a scar. It is a bad one for healing as you are not just healing one piercing but 2, if you catch it one end it will pull on the other that is why some piercers will recommend you get 2 piercings done first and once they are healed put a bar between them then, you just have to hope they heal straight enough to join the bar. Mine is a bad one for sleeping on, i have tiny thin ears and a massive bar so I have to try not to put too much pressure on it and try to sleep on the other side otherwise it gets angry, mine also took a good year to heal properly but as long as I don't sleep on it it's quite happy. Good luck.
Q:On the scaffolding sweeping pole, vertical and horizontal and vertical cross on the issue of conflict.
This kind of installation relative to the sandwich panel, if the substrate thickness of the same, due to the construction of more difficult, the cost is certainly higher, about 5-10 yuan
Q:determine tension in a wire holding a scaffold?
call L the tension in the left wire and R the tension in the right wire the sum of these tensions must equal the weight of the scaffold and box, so we have L+R=(420+95)g=5047N the torques due to the tensions and weights must sum to zero if the scaffold is not to rotate; let's sum torques around the left pivot point, if we do, then: the torque due to L=0 since there is no moment the torque due to the box = 420xgx2.2m=9055.2Nm the torque due to the scaffold = 95 x g x 3.5 = 3258.5Nm (assuming the scaffold has a uniform density, its weight acts at the center of mass) the torque due to R is 7R and is in the opposite sense from the torques from the weights; therefore we have 7R=3258.5+9055.2 =>R=1759.1N and the torque from the left is 5047-1759.1=3287.9
Q:Is my Scaffolding piercing infected?
ohh yess ! go to the doctor and get medication
Q:What is the level of the horizontal alert area when the high-rise building fastener type scaffolding is removed?

Fire time is 70 minutes. Thickness 50-150mm rock wool insulation board is basalt and other natural ore as the main raw material, rock wool insulation board by high temperature melt fiber, adding the right amount of binder, curing processing and made.

Q:What is scaffolding in early childhood?
Scaffolding Definition
Q:How do the townspeople in the Scarlet Letter react to Hester as she stands on the scaffold?
They react by mocking her. To Hester it is a humiliating experience. It is meant to be one. This reveals the childish nature of the puritanical society at the time. There is Aso a bit of irony in the fact that they are supposed to be looking down on her when intact literally, she is looking down at them because the scaffold is mounted about 4-5 feel up.
Q:Is it safe to use a 40' ladder supported by 6' scaffolding?
Generally No putting any other device (ladders) on scaffolding is against the OSHA regs (unless it is LARGE Area (defined in interpretation) and specific guidelines are met), and more than likely the Manufacturers policy (Highlight). You also have to think about fall hazards. If I was in charge of Safety on the site I would say NO, rent a JLG or more scaffolding. One section of scaffolding is NOT large area.
