Practice GATE ME laminate in the app →In composite design, BALANCED laminate means:SYMMETRIC laminate (about the mid-plane) is required to:Why is composite design called "concurrent" with manufacturing, unlike metals which are often "sequential"?Why is THICKNESS TOLERANCE harder to achieve in composites than metals?In composite drawings, each ply must be specified by:Around a CUTOUT or BOLT HOLE in a composite, the design challenge is:Damage tolerance in composite design relies heavily on:The choice between THERMOSET and THERMOPLASTIC matrices in composite design is driven by:In a TAPERED-thickness composite part, why are dropped plies always positioned INTERIOR to the stack (between Two parts of a composite assembly must mate to a metallic substructure within tight tolerance. The design apprIn Classical Lamination Theory (CLT), the laminate stiffness matrix is called the:In CLT, the A matrix relates which physical quantities?In CLT, the D matrix relates:What is the physical meaning of a NON-ZERO B matrix in a laminate?Which condition is SUFFICIENT to make B = 0 (zero coupling between in-plane and bending)?A laminate is called BALANCED if:A CROSS-PLY laminate consists only of:A SYMMETRIC CROSS-PLY laminate has which simplification in the ABD matrix?For a SYMMETRIC laminate, the 6×6 ABD system decouples into:In CLT, the assumption of "Kirchhoff's hypothesis" (plane sections remain plane and perpendicular to the referIn a SYMMETRIC laminate the inverse relations have the form: {ε°} = a·{N}, {κ} = d·{M}, where a and d are inveAn UNSYMMETRIC laminate cooled from cure temperature back to room temperature typically:The "EFFECTIVE engineering properties" of a symmetric laminate (E_x, E_y, ν_xy, G_xy) are computed FROM:Why is the IN-PLANE behavior of a symmetric laminate the SAME REGARDLESS of stacking order, while BENDING behaTo maximize BENDING stiffness D_11 of a laminate of fixed total thickness h, the 0°-fiber plies should be placWhat is QUASI-ISOTROPIC laminate, and when is it used?In a symmetric balanced cross-ply laminate, A_16 = A_26 = 0 simplifies which physical behavior?Why are most aerospace primary-structure composites laminates ALWAYS made SYMMETRIC (B = 0) even if some asymm
