1 - A unidirectional composite laminate reinforced with carbon fiber and epoxy resin matrix is given, with the following properties: • E1=157 GPa • E2= 10,8 GPa • G12=7,6 GPa • v12=0,27 Consider the following stresses in the principal directions (global coordinates): •?? = 257 MPa • ?? = 207 MPa • ?xy = 107 MPa • 0= 37° To determine: a) Flexibility matrix in local coordinates; b) Injury matrix in local regions; c) Stress matrix in global joints; d) Voltages in local regions (by the coordinate transformation matrix); e) Deformations in global negotiations (through local constitutive research). Observation: Use a Cramer Rule: f) Deformations at local locations (by the coordinate transformation matrix); g) Deformations in global negotiations (by coordinate transformation matrix) for verification. h) Flexibility matrix in global coordinates;

On January 1, 2024, Sheffield issued 10-year, $260,000 face value, 6% bonds at par. Each $1,000 bond is convertible into 30 shares of Sheffield $2 par value common stock. The company has had 10,000 shares of common stock (and no preferred stock) outstanding throughout its life. None of the bonds have been converted as of the end of 2025. (Ignore all tax effects.) (a) (b) (c) Assume that 75% of the holders of Sheffield's convertible bonds convert their bonds to stock on June 30, 2026, when Sheffield's stock is trading at $32 per share. Sheffield pays $50 per bond to induce bondholders to convert. Prepare the journal entry to record the conversion. (List all debit entries before credit entries. If no entry is required, select "No entry" for the account titles and enter 0 for the amounts. Credit account titles are automatically indented when amount is entered. Do not indent manually.)
