The following picture represents a bridge comprised by a continuous horizontal beam AB that has been stiffened by means of a set of pin joined bars. The structure is loaded on the right half of the beam by a distributed load of value w. Please notice that the only element that withstands bending moments is the beam AB All bars and beams sections are square solid 0,2m*0,1m, made of wood E=10 GPa, and max tension/compression=45 MPa. At the end you are requested to upload thesheet with all your calculations together with the ID Consider: a=5m, b=2m, w-300Kg/m Please answer to the following questions a. Order of Hyperstaticity DoH= b. Draw the Bending moment diagram in the beam AB highlighting value at the middle BM= c. Calculate Tension Compression loads in all the bars: Register here numerical value of load in the vertical bar Ncd= d. Assess potential buckling in the bars] e.

A wooden beam is fabricated by nailing together three pieces of dimension lumber as shown. The cross-sectional dimensions of the beam are also shown. The centroid is 3.4 in. below the top surface of the beam, and the moment of inertia about the z axis is 230.9 in.4. The beam must support an internal shear force of V = 365 Ib. If each nail can provide 120 Ib of horizontal resistance, determine the maximum spacing sfor the nails. 2 in. 4 in. 2 in. 2 in. 8 in. O 4.86 in. 8.32 in. O 7.91 in. 9.36 in. O 5.59 in.
