3b. Two blocks of wood are nailed together to form a T-beam shown in Figure. The allowable shear stress of the nail is 50 MPa, while the wood has an allowable shear stress of 20 MPa. Determine the maximum shear force (V) that can be applied to the beam considering both the allowable stresses of the nail and the wooden block. BONUS QUESTION: Explain briefly how you would increase the shear capacity of the cross-section without changing the allowable stresses of the nail and wood blocks. 240 lengths are in mm y=234 90 INA= 690780000 mm FIGURE Q3 340 *09
