Question 2 1 2.6 An aircraft has a total mass (m) of 2200 kg. The planform area (S) of the wings is 26.4 m² with a wingspan (2 xs) of 14.5 m. The wings are straight-tapered with a taper ratio (1) of and with a width at their root (centreline) chord equal to co. The quarter-chord is swept back at 22.5°. a) Show that the planform area (S) of wings is given by S = Co (1+1)s and calculate the root chord (co). b) What will be the change in the Aspect Ratio (AR) if the planform area (S) is kept the same whilst the wingspan (2 x s) is increased by 10%?

... 5m X 1m Water A wooden beam of specific gravity 0.64 is 150mm x 150mm x 5m is hinged as shown on one side and the other side floats on water. Take note that the location of the center of gravity of the beam (weight) is at the middle of the entire beam while the buoyant force will be located at the center of the beam that is only submerged in water. Determine the: a) the length of the beam "X" that is submerged in water and b) the angle the beam it creates along the horizontal, e A x = 2.3m B) x = 3.0m e = 30 degrees X = 2.7m E x = 2.0m F e = 19.47 degrees G e = 25.77 degrees (H) e = 21.74 degrees
