Chapter 1: Q11-39E (page 1)

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?

Short Answer

Expert verified

Breaking stress of alloy is 3.41脳107 Pa.

Step by step solution

01

The given data

Given that in a materials testing laboratory, a metal wire made from a new alloy is found to break when a tensile force of 90.8N is applied perpendicular to each end.

The diameter of the wire, d=1.84mm1m1000mm=1.84脳10-3m

Tensile force applied perpendicularly,F鈯�=90.8N

02

Formula used

Breaking stress of wire =F鈯�A

Where F鈯�is the tensile force applied to an object, A is the area over which force is exerted.

Let d be the diameter of the wire.

A=蟺d24

03

Find the breaking stress

Area=3.14脳1.84脳10-3m24=2.66脳10-6m2

Breakingstress=90.8N2.66脳10-6m2=3.41脳107PaPa

Hence, Breaking stress of alloy is3.41脳107Pa

A medical technician is trying to determine what percentage of a patient鈥檚 artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20脳104Pa, while in the region of blockage it is role="math" localid="1668168100834" 1.15脳104Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30.0 cm/s, and the specific gravity of this patient鈥檚 blood is 1.06. What percentage of the cross-sectional area of the patient鈥檚 artery is blocked by the plaque?
