A beam is created by nailing 3 planks together with 2 rows of nails as shown above. The beam exhibits a pin support at A and is suspended by a cable at B. A concentrated load of 10 kN is applied at the free end while a moment of 25 kNm is applied at location B. a) Determine the second moment of area (I) of the cross-section b) Draw the free body diagram, shear force diagram, and bending moment diagram of the beam c) For the maximum shear force on your SFD, determine the maximum and minimum shear stresses at the interface between the horizontal and vertical planks d) For the maximum shear force on your SFD, Determine the shear stress at the neutral axis
