Answer:
The total percent cold work done is 36.46%
Explanation:
Let initial metal thickness = T
Final metal thickness = t
The percent cold work done = WC
Then
%Wc = (T - t)/T × 100
% Wc = ( 0.096 - 0.061 )/0.096 ×100
Total %WC = 36.46%
Answer:
The total percent of cold work is 57.34%
Explanation:
Let x the initial thickness of the sheet. After 33% of cold working, the thickness is 0.096 in. Then:
x - 0.33x = 0.096
x = 0.143 in
the final thickness is equal to 0.061 in. The percent of cold work done is:
[tex]percent-of-cold-work=\frac{(initial-thickness)-(final-thickness)}{initial-thickness}*100[/tex]
[tex]percent-of-cold-work=\frac{0.143-0.061}{0.143} *100=57.34[/tex]%
