The reason for the higher value of theoretical strength of metals than the observed values needs to be explained. Concept Introduction: In the material science, a set of symmetrically same slip planes having directions for the dislocation motion resulting plastic deformation is described. The geometry of metal is changed due to an external force that causes the crystal lattice to slide over each other. The slip systems present in the material depends on the type of lattice. It specifically occurs in close-packed planes and in closed-packed directions. The magnitude is represented by the Burgers vector .

Question

Use PSpice to model the differential amplifier circuit shown in Fig. 4 in DIBO mode (double input balanced output). Use 2N3904 BJTs and use appropriate values for resistors (you can choose the values that will not lead to excessive gain and saturation) to demonstrate that the circuit provides differential amplification. Use Vcc = 5 and Vee = 5. Use a pair of sinusoids with opposing polarity (180 degree phase shift) as the inputs to the differential amplifier. Recall from the theory ic is needed to compute re. Make sure that the conditions set in the analysis of DIBO circuit are satisfied. Assume Rs1 = Rs2 50 Ω. Does your simulation match the theoretical gain? Explain any differences.

Derive the expression for the voltage gain of DIBO differential amplifier using AC analysis.

The timber floor framing for a building comprise floor joists using 2" wide nominal lumber is to be constructed as shown in Fig. 1. The Dead load (D) = 26 lbs./ft² (inclusive of joists and flooring) and the live load L= 40 lbs./ft². Lateral torsional buckling is prevented for all members and normal service conditions and temperatures are expected. (i) Design the floor joists using 2" wide nominal lumber using Southern Pine No. 1 (ii) Design the floor beams using Caribbean Pitch Pine (Select Structural). (Assume a 8" x 14” trial section to estimate beam self-weight for your initial design). Density of Caribbean Pitch Pine = 50 lbs/ft³ (800 kN/m³).
