IV. An annealed copper strip 9 inches wide and 2.2 inches thick, is rolled to its maximum possible draft in one pass. The follow

Irina-Kira [14]

Answer:

13.9357 horse power

Explanation:

Annealed copper

Given :

Width, b = 9 inches

Thickness, $h_0=2.2$ inches

K= 90,000 Psi

μ = 0.2, R = 14 inches, N = 150 rpm

For the maximum possible draft in one pass,

$\Delta h = H_0-h_f=\mu^2R$

$=0.2^2 \times 14 = 0.56$ inches

$h_f = 2.2 - 0.56$

= 1.64 inches

Roll strip contact length (L) = $\sqrt{R(h_0-h_f)}$

$=\sqrt{14 \times 0.56}$

= 2.8 inches

Absolute value of true strain, $\epsilon_T$

$\epsilon_T=\ln \left(\frac{2.2}{1.64}\right) = 0.2937$

Average true stress, $\overline{\gamma}=\frac{K\sum_f}{1+n}= 31305.56$ Psi

Roll force, $L \times b \times \overline{\gamma} = 2.8 \times 9 \times 31305.56$

= 788,900 lb

For SI units,

Power = $\frac{2 \pi FLN}{60}$

$=\frac{2 \pi 788900\times 2.8\times 150}{60\times 44.25\times 12}$

= 10399.81168 W

Horse power = 13.9357

Explain the methods of case hardening in terms of material engineering

WARRIOR [948]

Answer:

Case-hardening involves packing the low-carbon iron within a substance high in carbon, then heating this pack to encourage carbon migration into the surface of the iron. This forms a thin surface layer of higher carbon steel, with the carbon content gradually decreasing deeper from the surface.
