3. The plot below of load vs. extension was obtained using a specimen (shown in the following figure) of an aluminum alloy. The crosshead speed was V = 3.3x10-4 inch/second. The extension was measured using a 2" extensometer as shown (G). Eight points on the plastic part of the curve have been digitized for you. Use these points to help answer the following questions. 900 Load, pounds 800 700 (0.10, 630) 600 (0.30, 729) (0.50, 745) (0.20, 699) (0.40, 741.5) 500- (0.004,458) 400 (0.0018, 405) 300 200- 100 100 (0.80, 440) D=3.3" 0.03" G-2.0" 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 80 Extension, inches A) Determine the following quantities.

A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).
Q1/For the following write either True or False and correct the false sentences. 1- Static stability is a necessary condition for an aircraft but not sufficient condition for dynamic stability. 2- The aerodynamic center (AC) is the point on the wing about which the coefficient of pitching moment is negative. For static stability, the center of gravity must be in front of stick fixed neutral point NP (NP > h). dCi <<0 T 4- The condition for an aircraft to be laterally stable is that 5- The motion of the aircraft around its longitudinal axis is called yaw. do
