Asbestos is a fibrous silicate mineral with remarkably hightensile strength. But it is no longer used because airborne as-bestos particles can cause lung cancer. Grunerite, a type of as-bestos, has a tensile strength of 3.5x10^2kg/mm²(thus, a strandof grunerite with a 1-mm2cross-sectional area can hold up to 3.5x10²kg). The tensile strengths of aluminum and Steel No.5137 are 2.5104lb/in²and 5.0104lb/in², respectively. Cal-culate the cross-sectional area (in mm²) of wires of aluminumand of Steel No. 5137 that have the same tensile strength as afiber of grunerite with a cross-sectional area of 1.0μ m²
