Q:In the Scarlet Letter, when Dimmesdale asks Hester who Chillingworth really is, why does she keep her oath to him of not revealing that he is her husband? Guilt? Morals? Thanks
Because she owes him since she cheated on him.
Q:i had it done 2/3 months ago, it was fine at first but now on each end i have two lumps on my ear:S there relitavely smal...the size of like a really tiny pea.there really painfull and sore and quite red and sometimes they scab over with yellowy crust [yes i know sounds disguisting]im just a bit worried that its gone all weird or are these normal? am i cleaning it right?
I had the same situation occur when I got my scaffold/industrial done. I wouldn't be too concerned. The lumps are called hypertrophic scars, and supposedly they are pretty common and are caused by overcleaning, harsh products, or (as I think was my case) general irritation from the jewelry moving repeatedly back and forth through the piercing or being bumped around or rubbed/touched. Mine lasted quite a long time. Try leaving your piercing alone for a couple of days. Then salt water solutions or compresses are supposed to help the lumps to heal, and I also used tea tree oil and neosporine intermittently. Hot compresses like a heated washcloth applied to the area help to reduce the lumps, as well. Sometimes it's recommended to try another type of jewelry, like titanium, or switch temporarily to two separate bars. You might also try finding a really gentle cleanser/soap. I just kept my original piercing, using the above techniques off and on, and after months of the lumps remaining red and sore, they just went away totally. Just keep your eye out for any pussing (hypertrophic scars ooze, but they don't usually pus), increased swelling, and the area feeling very hot- these are signs of infectiona nd you should see your doc right away. Good luck! :)
Q:What does scaffold one's days mean? kill time?
In 60 years of using English in Britain I have not come across that expression, so it is probably rare. Scaffolding is put up to help build or repair tall buildings, so possibly that expression means 'to do something useful with one's time.' But a scaffold is also, historically, a place of execution (legal killing of prisoner), so the expression could mean indeed 'wasting time'. I have a faint feeling that 'scaffold one's days' was written by a non-native speaker of British English. It may be more common in the USA.
Q:A scaffold is constructed by placing two supports under a 13 ft, 9 in (a) board weighing 84 lbs. The supports are each 2 ft, 8 in (b) from their respective ends. Two painters stand on the board; one weighs 158 lbs and stands 4 ft, 11 in (c) from the left end of the board. Where must the 222 lbs painter stand so that each support carries the same weight? (express your distance in feet from the right end of the board (d).)please help!! thanks(:
Total weight = 222 + 158 + 84 = 464 lb So, each support must carry 232 lbs Working in inches: Take moment about Right hand end Board is assumed to be uniform - CG is at the center (232 x 32) + (232 x 133) = (158 x 106) + ( 84 x 82.5 ) +(222 x d)7424 + 30856 = 16748 + 6930 + 222d 222d = 14602 d = 65.77 inches Distance of 222 lb painter should be 5ft 5.77inches from Right end
Q:improper design of formwork and scaffolding, not adequate braces and supports, improper handling, corrosion of material is several factor of formwork and scaffolding failure. it is estimated that more than 3000 accidents involving falls from scaffolds and 30 fatalities
I believe that you have covered it all. Improper handling covers my first thought; workers carelessness by not following safety guidlines
Q:Rather than buy tensile steel rods to reinforce concrete I wonder whether I can effectively recycle scaffold tubes that are presently on my roof.
You can, but I can think of two reasons why it might be unwise. Firstly, reinforcing bars are ribbed to provide a key between the concrete and the steel, whereas scaffolding bars are much smoother. This leads me to believe that scaffolding bars, weight for weight, wouldn't be as effective as reinforcement bars and you wouldn't have as much reinforcing action as you think. In extremis, you could end up with an under-reinforced concrete beam which will be brittle - reinforced concrete is usually deliberately slightly over-reinforced so that the behaviour close to failure is ductile, as it gives you time to run away. Secondly, scaffolding bars are hollow and reinforcement bars are solid. In reinforced concrete, the alkalinity of the cement paste helps to protect the reinforcement from corrosion - the reason for specifying a minimum cover - but the inside of your scaffolding bars would not benefit from this and so I'd worry about the risk of shortened life due to rusting from the inner face. At least when reinforcement bars rust they tends to spall the concrete cover off, which you see happening.
Q:I'm gonna be getting piercings this weekend, so i know im already getting my nose. but i want to get my ear. like barbell? so what's the difference between Scaffold and Industrial?
They're the same thing. Different places call them different things.
Q:What are scaffold spanners used for?
Ratchet Podger Spanners...Aluminium Scaff Spanners Spanners are wide wrenches that are made from durable metals. Spanners are made specifically for scaffolding and are designed to fit into the tool belt nicely. Spanners are very useful for a number of jobs and are often used along with other scaffold tools on a safety lanyard to prevent dropping the tool to the street below. Spanners work the same as traditional wrenches but like many scaffolding tools are made with a hole in the end of the wrench for the safety strap to be inserted through. Stainless steel and aluminum are the most commonly used metals for spanners to ensure durability even if the item is dropped from high.
Q:How to calculate the vertical force of scaffolding
The maximum reaction force of the rod support is calculated, and the maximum bending moment and deformation are calculated under the most unfavorable load arrangement1 load calculation2 Calculation of bending strength: maximum bending moment calculation for large bar weight uniform load and load distribution of the bending moment and the most unfavorable value3 deflection calculation: the maximum deflection is considered as the calculation of the load distribution of the load and the load of the large span
Q:Write a scaffold method for 743,425 divided by 365EASY 10 points
use a calculator you punk, nobody writes out division anymore, grab your ti-84 and type it out... there's your scaffold method jerk.
