Question

2. 0.9 m 9000 N Aluminum Composite Panel (ACP) is a type of flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACPs are frequently used for external dadding of buildings (building facades), for insulation and for signage. Eacat's Snaceshi Farth is an example of the use o 凸CP n architecture. It is a geodesic sphere composed of 11 324凸CP tiles. A 0.9 m ong by 8 mm thick panel is constructed o two 0,4 mm thick aluminum panels ith a lo density polyethylene LDPE core. A 9000 Newton load is applied to the panel. The modulus of elasticity of the aluminum is 69 GPa, while the modulus of elasticity of the LDPE is 0.4 GPa EXAMPLE NOTES EDCUNTSTATSHELP Part Description Answer Chk History A: 6480 What is the oross sectional area of mm 2 the LDPE core? include units with answer A. # tries: 3 Eno 0.00640 H1 m*2 Try 5-your answer of 403.65 Pa is not correct.
