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

Lastly, the 0.7's is as thus:
The combined steam and leaf plot is:
Answer
63 %
Explanation:
It is given that the reservoirs is at the temperature of 627°C and 27°C
So lower temperature that is = 60°C=273+60=333 K
And the higher temperature that is = 627°C =273+627=900 K
We know that the thermal efficiency of thermal reservoir = 1- =
= 0.63 =63 %
So the efficiency of the reservoir is 63%
