Actually I read it more like

K3 : the sky is blue
Craptor : no the sky is red. my professional friend told me
K3 : No, come out of your cave and you can see the sky is blue
Craptor : f*ck off you parasite I know for a fact the sky is red. I have all this cave drawings in my cave that says the sky is red
K3 : I am standing right outside your cave looking at the sky, i'm telling you it is blue.
Craptor : 1 + 1 equals 2, therefore the sky is red, see I proved it. You have no evidence the sky is blue.
K3 : what does 1 + 1 have anything to do with the sky?!
Craptor : you parasite so dumb of course don't understand, f*ck off because I have proof I am right and you are wrong.
K3 : but I am standing right here.........
Craptor : squirrels!!

LESSON : don't waste your time with the nutjob that lives in his cave and paint his own pictures.

nah

I not sure you learn about density for steel or not anyway.... Just hope that i not going wrong

V (Volume) = m (Mass) x p (Density)

Steel's density is about 7700kg/m^3

if you claim that the metal bar is 50 kg
then the calculation call be below

V = 50kg x 7700kg/m^3
V = 0.006 m^3

with the cube root of 0.006m^3 then you'll have 0.180m solid cube block do you have any idea how big is  a 0.180m cube?

this is based on a cube if you go to the shape some like "rod" like the antiroll bar the diameter even bigger and the length even longer

Lancer anti roll bar 20mm (diameter)

V = h (height) x pi (3.142) x r^2 (radius)

thus,

0.006m^3 = h x 3.142 x 0.01^2

h = 0.006m^3 / (3.142 x 0.01^2)

h = 20m

Does the anti looks like it has 20m in length?
