If possible, answer in 3 decimal places, thank you. For the wood beam shown in Figure A, assume L=1.5 m and P=8 kN. The beam cross section shown in Figure B has dimensions of b=47 mm and d=232 mm. (a) Determine the maximum horizontal shear stress in the beam. (b) If the allowable shear stress for the wood is 800 kPa, what is the minimum width b that is acceptable for this beam? Calculate the reaction forces By and Dy acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown for the forces By and Dy on the free-body diagram below. (Note: Since Dx=0, it has been omitted from the free-body diagram.) By= kN Dy= kN Determine the shear forces VA⁢B, VB⁢C, and VC⁢D acting in segments AB, BC, and CD, respectively. Note that the shear force is constant in each of these segments. When entering your answers, use the shear force sign convention. VA⁢B= kN VB⁢C= kN VC⁢D= kN…

!! Show Complete & Detailed Solution w/ FBD !!The concrete post in the figure, is reinforced axially with four symmetrically placed steel bars, each ofcross-sectional area 750 mm2. The moduli of elasticity are 200 GPa for steel and 14 GPa for concrete. A 2000-kN axial load is applied. Compute the:a. axial force in concrete;b. axial force in the steel bars;c. stress in the concrete;d. stress in the steel bars;e. deformation of the concrete post.
A 200 mm × 220 mm timber post is subject to an unknown axial compressive load(F) that is eccentric to both principal axes as shown below. If the axial stress is2.4 MPa then:(a) What is the compressive load?(b) What are the applied moments in the x and y directions?(c) What are the moments of inertia in the x and y directions.(d) At what corner does the maximum stress occur? State whether it is tensile or compressive?` (e) Calculate the maximum stress at the corne
