A brass wire is to withstand a tensile force of 350N without breaking? A brass wire is to withstand a tensile force of 350N without breaking.

Answer: First you need to find the Breaking Stress of Brass (Ultimate Strength)

4.7*10^8

Then use the formula

(Tensile Force) / (Cross Section area) = Breaking Stress

Plug in Values

350/pi * (radius) ^2 = 4.7*10^8

From here simply solve for r and then multiply r by 2 and get your diameter
