2) Transverse shear(10pts). The beam is slit longitudinally along both sides. The cross-section shown is subjected to an internal shear force V=300kN. Determine the shear stress by the seam at the junction of top and middle pieces (junction A). If the two slits are welded, will the shear stress at A be bigger or smaller? 100 mm 25 mm- 25 mm 200 mm 25 mm 200 mm 25 mm 5 mm
