5.5-23 A beam ABC with an overhang from B to
C supports a uniform load of 3 kN/m throughout its
length (see figure). The beam is a channel section with
dimensions as shown in the figure. The moment of iner-
tia about the z axis (the neutral axis) equals 210 cm*.
(a) Calculate the maximum tensile stress o, and
maximum compressive stress o, due to the
uniform load.
(b) Find the required span length a that results in
the ratio of larger to smaller compressive stress
being equal to the ratio of larger to smaller ten-
sile stress for the beam. Assume that the total
length L = a + b = 6 m remains unchanged.

If you were manufacturing a precision component which has a mass of around 15 grams and which was a solid 3D shape, which method would be appropriate?
What are "no-bake" molds, and how do they compare to green sand molds? a) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with resins that do not need heat in order to cure. The result is a mold that can maintain better dimensional control over high production volume. b) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with fine wood chips. They are then compressed with high pressure without baking. c) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with dry clay that do not need heat in order to cure. The result is a mold that doesn't require and baking. d) "No Bake" molds is the same as the tradition clay-and-water but used in high production volume.
