Answer:
The answer is below
Explanation:
Given that:
ρ = 800 kg/m3, c = 600 J/kg-K, k = 40 W/m-K, Initial temperature = Ti = 1150,
Environment temperature = T = 450 K, Final temperature = T∞ = 325 K
Diameter = 10 mm = 0.01 m, A = 6
The estimated time for cooling process (t) is given as:
The estimated cooling time is 589 s
It was determined by the forensic engineers that the historic collapse of the Minneapolis Interstate Bridge was due to design and construction flaws. It led to the collapse of the structure.
<h3>What is the Minneapolis Interstate Bridge?</h3>
The Minneapolis Interstate Bridge is a well-known bridge that was constructed in Minneapolis city in 1967.
It has been demonstrated that the collapse of this bridge constructed in Minneapolis was due to its inadequate load capacity.
In architecture, it is fundamental to measure the amount of weight that a structure (in this case, a bridge) can sustain in a given period of time.
