A 2x6 (1.5 inch by 5.5 inch) edgewise beam is used to carry the load specified above. The beam has 3 inches of bearing length at each end support. The bending strength is 2500 psi, shear strength is 170 psi, the modulus of elasticity is 1.5x106 psi, deflection limit is L/240 and the compression perpendicular to grain is 600 psi. Find the following values to design the beam; a. The maximum shear force
b. The maximum moment
c. The value of the deflection limit
d. The bending stress in the beam
e. The shear stress in the beam
f. The maximum deflection in the beam
g. The maximum bearing stress at the support
h. Does the beam fail?

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
