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
Answer:

Explanation:
The first thing we will do is convert the units. Miles per hour to meters per second.


Performing the operations

Now, we will use the acceleration formula

Where v = speed and t = time
Substituting the values of
