Answer 1

Question

Chapter 44, Problem 1RQ

To determine

The reason for atoms of a conductor usually contains valence electrons.

Expert Solution & Answer

Explanation of Solution

Conductors are formed from materials which have large and heavy atoms. Most of materials which conducts are metals. Conductors are formed from the atoms which usually have one or more electrons in their valence shell.

An atom with only one valence electron is the best electrical conductor because of the loosely held electron orbit and it can be easily abandoned for current flow. Thus the conductors have electrons with one or two electrons in the valence shell.

250 mm 400 mm A B C E F 250 mm PROBLEM 1.52 Each of the two vertical links CF connecting the two horizontal members AD and EG has a 10 × 40-mm uniform rectangular cross section and is made of a steel with an ultimate strength in tension of 400 MPa, while each of the pins at C and F has a 20-mm diameter and are made of a steel with an ultimate strength in shear of 150 MPa. Determine the overall factor of safety for the links CF and the pins connecting them to the horizontal members. 24 kN

50 mm 12 mm B O C OA 300 mm 450 mm E PROBLEM 1.51 Each of the steel links AB and CD is connected to a support and to member BCE by 25-mm-diameter steel pins acting in single shear. Knowing that the ultimate shearing stress is 210 MPa for the steel used in the pins and that the ultimate normal stress is 490 MPa for the steel used in the links, determine the allowable load P if an overall factor of safety of 3.0 is desired. (Note that the links are not reinforced around the pin holes.)
