Three questions there, let me try to organize them.

a) Cite five factors that lead to scatter in measured material properties.

b) Upon what three criteria are factors of safety based?

A large tower is to be supported by a series of steel wires.  It is estimated the load on each wire will be 15,000 N.  Determine the minimum equired wire diameter, assuming a factor of safety = 2.0 and a yield strength of 800 MPa (125,000 psi) for the steel. Reflect by commenting on the meaning of your answer.

Where,

Working stress

Allowable working unit stress

N= Factor of safety

Given the information we have,

Diameter and force are related by,

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer: report them
