Answer:
The maximum load the bar can withstand = 35.43 KN
Explanation:
Ultimate tensile strength of the given aluminium bar [tex]\sigma[/tex] = 540 M pa
Cross section area of the bar = [tex]8.1^{2}[/tex] = 65.61 [tex]mm^{2}[/tex]
We know that the ultimate strength of the bar is calculated from
[tex]\sigma = \frac{P_{max} }{A}[/tex]
[tex]540 = \frac{P_{max} }{65.61}[/tex]
[tex]P_{max}[/tex] = 540 × 65.61
[tex]P_{max}[/tex] = 35.43 KN
Therefore the maximum load the bar can withstand = 35.43 KN
