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: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:Pain on a scale of 1-10Advice on piercing?I heard it's easily infected??

Pain will differ from person to person so no one can really answer that. My advice is to sleep with your arm bent under your head so your ear is in that little whole and nothing can bother it. Also, avoid dying your hair for the next two months and be care when putting on sweaters, shirts, brushing hair, et cetera. Infection is a problem if you keep it clean but irritation is because every time you bump on side, you bump the other as well. Good luck!

Q:Also if its possible part B wants to know A ball thrown vertically upward is caught bythe thrower after 2 s.Find the initial velocity of the ball. Theacceleration of gravity is 9.8 m/s2Answer in units of m/sFind the maximum height it reaches.Answer in units of m

A) Speed of falling brush = at =9.8 x 3.39 = 33.22m/sec B) Vertical distance Y = Vo x t - 0.5 x at^2 0 = Vo x 2 - 0.5 x 9.8 x 4 Initial Velocity = Vo = 9.8m/sec^2 Vertical height = Vo^2/2g = 9.8^2/2 x 9.8 = 4.9m
