Q:A man of mass 74.4 kg stands on a scaffold supported by a vertical rope at each end. The scaffold has a mass of 21.9 kg and is 3.9 m long. Suppose the man stands to the right from the middle of the scaffold that is a distance one sixth of the length of the scaffold. What is the tension in the right rope? b) What is the tension in the left rope? thanks in advance.

Left rope = T1 Right rope = T2 1/6 of 3.9 m = 0.65 m 3.9/2= 1.95 1.95 - 0.65 = 1.3 m from right rope. Take g = 10m/s^2 T1 = ((219 x 3.9)/2) + (744 x 1.3) = 1394.25 1394.25 = 3.9 x T1 1394.25/3.9 = T1 = 357.5 N (answer for left rope) T2 = ((219 x 3.9)/2) + (744 x (3.9 -1.3)) = 2361.45 2361.45 = 3.9 x T2 2361.45/3.9 = T2 = 605.5 N (answer for right rope)

Q:Please advise the construction industry experts: residential full scaffolding inside the frame how to calculate the number of steel pipe needs, pay attention, I asked how many meters! Or tell me how many meters per square meter of steel pipe? And then attached to the high requirements, thank you For example: now a layer of 1000 square meters area, a total of 10 standard layer of residential buildings, 3 meters high! How to calculate the amount of steel required to do a layer? The amount of steel pipe in meters, or tonnage units.

Steel pipe commonly used specifications for 1m-6m first determine your height and length, width

Q:so im 16 and only got into piecings within like the last year...iv only got my belly done, but iv been in love the scaffold piercing for ages, but im just wondering whether it would look really odd if i got it as it would be the only ear piecing i had, opinions??(and yes if i got it done i would go to a reputable place)

I pierce lots of Industrials on young girls and half of them say its their first piercing! They look great on a plain ear, because they are such a large piercing its good to have ears that arent covered in piercings already because it starts to look too much when you have heaps of piercings in your ears. You just need to be dedicated to it as it can be difficult to heal, so make sure you have a really good think about it before you get it done.

Q:a paintbrush falls from a scaffold takes 3 sec to hit the ground. How high is the scaffold? Explain pls!?

1) In three seconds the paintbrush accelerated to a speed of 96 feet/sec (ignoring air resistance) at a acceleration of 32 feet/sec/sec. 2) It started at a speed of zero, so the average speed for those three seconds was 48 feet/sec. 3) 3 seconds times 48 feet/sec. equals 144 feet.
