Answer:
The difference in diameter between the two ends is 1.757''
Step-by-step explanation:
Given;
length of a bar of cast iron, L = 18.125"
initial diameter of the bar, d₁ = 0.983"
final diameter of the bar, d₂ = 2.74"
The difference in diameter between the two ends of the bar is calculated as;
difference in diameter = d₂ - d₁
difference in diameter = 2.74" - 0.983"
difference in diameter = 1.757''
Therefore, the difference in diameter between the two ends is 1.757''
