1. Locate the shear center for the closed section shown. Assume the areas for stringers 1, 3, 4, 6 = 650 mm², and for 2, 5 = 1300 mm². Also, assume the thicknesses are all the same as 2.5 mm. Hint: consider the direction of all the shear flows in CCW (Counterclockwise) direction and assume q61 = 96, q12 = Q1, Q23 = q2, q34 93, 945 = 94, 956= qs, and solve for all shear flows in terms of 96. 2.5mm 100 mm 100mm 250mm A 300mm 175mm 75 mm
