Exercise 6.5 Compute the stresses in laminate coordinates at top and bottom of each lamina in Example 6.1 (p. 178) when the laminate is subjected to ?0x = 765(10?6) mm/mm, ?0y = ?280(10?6) mm/mm, ?xy = 34.2(10?6)1/mm and all remaining strains and curvatures equal to zero.

Note: this is Example 6.1 Compute the coefficients in the plate stiffness equations (6.9) for a two- lamina laminate with ?1 = 55?, ?2 = ?55?, t1 = t2 = 0.635 mm

with material properties given E1 = 19.981 GPa, ?12 = 0.274, E2 = 11.389 GPa, G12 = G13 = 3.789 GP a [172]. assume the out-of-plane shear modulus G23 ?= Gm = 0.385 GP a.

Many studies have suggested that there is a link between exercise and healthy bones. Exercise stresses the bones and this causes them to get stronger. One study examined the effect of jumping on the bone density of growing rats. There were three treatments: a control with no jumping, a low-jump condition (the jump height was 30 centimeters), and a high-jump condition (60 centimeters). After 8 weeks of 10 jumps per day, 5 days per week, the bone density of the...

The first cake has three layers with each one having a different top view: the bottom is a square, the middle is a hexagon, and the top is a circle. The height of each layer may vary. The second cake has three layers with a top view of concentric circles. All three layers have the same height. The diameter of the middle layer is 20% larger than the top layer, and the diameter of the bottom layer is 25% larger...

4)“Bottom-up” vs. “Top-down” Perceptual Processing a). Bottom-up processing – define/ explain what it is. b)Top-down processing - define/ explain what it is. You can use this example: Ca_yo_re_dt_is_en_en_e? C). In perception, bottom-up and top-down processing are believed to occur simultaneously. Explain what that means.
