Answer:
factor of safety is 1.756
Explanation:
given data
torsional yield strength = 0.43 sut
maximum shear stress = 434 MPa
A = 2170 MPa
m = 0.146
diameter = 4 mm
to find out
factor of safety
solution
we know 1 sut is equal to 1772.39 MPa
so 0.43 sut = 0.43 ×1772.39 = 762.128 MPa
so here
factor of safety formula is
factor of safety = yield strength / shear stress ............1
put here value
factor of safety = 762.128 / 434
Answer: At 520 feet between the piers, the center arch of Eads Bridge was the longest rigid span ever built at the time of its construction (only a few suspension bridges had longer spans).
cross-weight is used to tighten it up.
and yes this is important because Cross-weight percentage compares the diagonal weight totals to the car's total weight.
hope this help
