Answer:
Explanation:
From the given question:
Using the distortion energy theory to determine the factors of safety FOS can be expressed by the relation:

where; syt = strength in tension and compression = 350 MPa
The maximum shear stress theory can be expressed as:

where;

a. Using distortion - energy theory formula:



FOS = 2.183
USing the maximum-shear stress theory;




FOS = 1.977
b. σx = 110 MPa, σy = 100 MPa
Using distortion - energy theory formula:




FOS =3.322
USing the maximum-shear stress theory;



FOS = 350/2×25
FOS = 350/50
FOS = 70
c. σx = 90 MPa, σy = 20 MPa, τxy =−20 MPa
Using distortion- energy theory formula:



FOS = 350/88.88
FOS = 3.939
USing the maximum-shear stress theory;





FOS = 4.341
Answer:
diesel engine
Explanation:
because diesel is stronger than petrol
Answer: heat loss through wall is 16.58034kW
Temperature of inside wall surface is 47°c
Temperature of outside wall surface is -2.7°c
Explanation:detailed calculation and explanation is shown in the image below.
Answer:
Either D or C
Both of these masks are used for dust, but since half masks are generally cheaper and easier to use, I'd go with C.
If this is correct, I'd appreciate a brainliest.
Answer:
Responsibility
Explanation:
By stamping the drawings that he was looking over, Jack Gillum conveys the fact that he is accepting responsibility for this work. The purpose of Gillum's stamp is to explain that such work has been under engineering review, and that it has fulfilled all the requirements that he watches our for. By putting his stamp in this work, Gillum accepts responsibility in case an error or a discrepancy is found in the drawings.
