Using MATLAB create a code to locate the centriod and moments of interia about the centriod of a stiffened rectangular plate with or without cut outs,

A continuous and aligned fiber-reinforced composite having a cross-sectional area of 1190 mm2 is subjected to an external tensile load. If the stresses sustained by the fiber and matrix phases are 144 and 2.16 MPa, respectively, the force sustained by the fiber phase is 74400 N, and the total longitudinal strain is 0.00119, determine the following: (a) The force sustained by the matrix phase (in N). (b) The modulus of elasticity of the composite material in the longitudinal direction (in GPa). (c) The modulus of elasticity for the fiber phase (in GPa). (d) The modulus of elasticity for the matrix phase (in GPa).

Compute the longitudinal tensile strength of an aligned glass fiber-epoxy matrix composite in which the average fiber diameter and length are 0.0155 mm (0.60 × 10-4 in.) and 1.07 mm (0.042 in.), respectively, and the volume fraction of fibers is 0.38. Assume that (1) the fiber-matrix bond strength is 100 MPa (14,500 psi), (2) the fracture strength of the fibers is 3500 MPa (5 × 105 psi), and (3) the matrix stress at composite failure is 5.5 MPa (800 psi).

2.Define in detail the terms science and technology. How are these terms different, similar and what is the connection between them? Define in detail the terms invention and innovation. Are there any differences, similarities and connection between them? Why? As part of your description include an example of each type.

A facility that manufactures fireworks has a large increase in production every June, such that their peak electrical demand is 101, while in every other month of the year their peak electrical demand of 50. The local utility informs the client that they will be changing the rate structure. The demand charges will decrease from $7.54/kW to $5.37/kW. But the utility will start imposing a ratchet clause at 80% of peak demand. What will be the expected change in annual demand costs for the facility? (When entering your answer, please note that a positive # indicates that the facility costs will increase, whereas a negative # indicates that the facility costs will decrease.)
