Problem 39E

In a materials testing laboratory, a metal wire made from a new alloy is found to break when a tensile force of 90.8 N is applied perpendicular to each end. If the diameter of the wire is 1.84 mm, what is the breaking stress of the alloy?

Step-by-Step Solution:
Step 1 of 3

Solution 39E Mathematically, the relationship between tensile force and stress is given by Stress = Tensile force /Area…..(1) Given, diameter of the wire = 1.84 mm Its radius = 0.92 mm = 0.92 × 10 3m 3 2 2 Area of cross-section of the wire A = × (0.92 × 10 ) m 6 2 A = 2.65 × 10 m Tensile force F = 90.8 N Therefore, from equation (1), Stress = 90.8 N/(2.65 × 106m )2 7 Stress = 3.41 × 10 Pa 7 Therefore, the breaking stress of the alloy is 3.41 × 10 Pa.
