Answer:
square cross section. The bar is made of a 7075-T6 aluminum alloy which has a yield strength of 500 MPa, a tensile strength of 575 MPa, and a fracture toughness of 27.5 MPaâm.
Required:
a. What is the nominal maximum tensile stress on the bar?
b. If there were an initial 1.2 mm deep surface crack on the right surface of the bar, what would the critical stress needed to cause instantaneous fast fracture of the bar be?
C, because a narrow structure evacuation below surface ground isn’t the best and a structure holding forces and isn’t to do with the question at all and d doesn’t matter if there include away or not
Answer:
solution in the picture attached
Explanation:
Answer:
429.5 ft
Explanation:
We are told that;
1 ft = 0.305 meters
We want to convert 131 meters to ft, by proportion we have;
Distance = (131 × 1)/0.305
Distance = 429.5082 ft
We want to approximate to the nearest tenth of a foot.
This gives us;
Distance = 429.5 ft
