1. Draw the complete outline of the problem.
2.to find the heat Raise the heat transfer equation for cylinders from the inside of the metal tube, to the outside of the insulation.
3. Once the heat is found, Pose the heat transfer equation for cylinders from the inner part of the metal tube to the outside of the metal tube and solve to find the temperature
Answer:
The maximum load the bar can withstand = 35.43 KN
Explanation:
Ultimate tensile strength of the given aluminium bar = 540 M pa
Cross section area of the bar = = 65.61
We know that the ultimate strength of the bar is calculated from
= 540 × 65.61
= 35.43 KN
Therefore the maximum load the bar can withstand = 35.43 KN
