Here is the derivation of that D2/162.2, Weight of steel bar per meter = Area of the steel x Density of steel x Bar length. = (3.14 x D2 /4) x 7850 kg/m3 x 1m (refer these posts basic formulas & unit weight of materials) = (D2 x 6162.25)/(1000 x 1000)
An Olympic curl bar is much lighter than a barbell, weighing only 15 to 20 pounds, and is about 47 to 48 inches long. It can, therefore, be used to lift weights less than 45 pounds as well. Maximum weight capacity for most standard curl bars is about 200 pounds. Standard two-arm curl bars have a 1-inch sleeve on each end, and accept any standard weight plates. These are commonly used in home gyms. Olympic curl bars have a 2-inch sleeve, and they're designed to accommodate slightly bigger weight plates that are commonly found in the gyms.
