[QUOTE="TeeTex, post: 6015732, member: 645775"] Yes like for example Each tree is made by iron wire structure a translucent paper cone open at the bottom. The metallic structure of the decoration is obtained welding on the basic circumference two linear pieces corresponding to two apotems of the cone. The weight of the paper used is p1 = 25g = m2, and each conical cover is obtained from a sheet 35 cm square on the side. The weight of the wire is instead equal to p2 = 0; 08g = cm, while the electric apparatus (lamp holder, bulb and cable) and the bill hook weigh 30 g per each decoration. Each suspension point of the support can bear a maximum weight of 40 g. The single tree is tantopièu decorative, how much greater is the luminous surface (therefore the base does not count). Determine the optimal measures of decoration [Translated from other language] [/QUOTE]
