Support Elastic
Could someone take a min and help me with this physics problem please?
An acrobat of mass 55 kg is going to hang by her teeth from a steel wire and she does not want teh wire stretch beyond its elastic limit. The elastic limit for the wire is 2.5 x 10^8 Pa. What is the minimum diameter the wire should have to support her?
1Pa = N/m²
Weight of acrobat = 55*9.8 =539N
Area of wire = Xm²
elastic limit for the wire = 2.5*109 N/m²
539/ Xm² = 2.5*10^8/1
Xm² = 539/2.58*10^8
Area of wire = 2.08*10^-6m²
There are 1.0*10^6 mm² in 1.0m²
Therefore the cross sectional area of the wire must me 2.08mm²
Radius of wire = 3.14159 * r² = 2.08
Radius of wire = √0.6621mm
radius of wire = 0.814mm
Diameter of wire = 1.63 mm
