Problem $04\mathrm{.}104-$ Comparing different materials laser heating $-$ DEPENDENT MULTI$-$

PART PROBLEM $-$ ASSIGN ALL PARTS

Thick slabs of stainless steel $(k=14\mathrm{.}9\frac{W}{m}*K$ and $a=3\mathrm{.}95{10}^{-6}\frac{m^2}{s})$ and copper $(k=401\frac{W}{m}*K$

and $a=117{10}^{-6}\frac{m^2}{s})$ are placed under an array of laser diodes, which supply an energy pulse of $5$

${10}^7\frac{J}{m^2}$ instantaneously at $t=0$ to both materials. The two slabs have a uniform initial temperature

of $29C.$

Array of laser diodes

Problem $04\mathrm{.}104.$a $-$ Stainless steel's temperature with laser heating

Determine the temperature of the stainless steel slab, at $5$ cm from the surface and $60$ s after receiving an energy pulse

from the laser diodes. $($You must provide an answer before moving to the next part.$)$

The temperature of the stainless steel slab is

$C.$
