Prob. 6.4-6. (a) A glued, laminated (glulam) beam is made by gluing together n planks of width b and thickness 1, as illustrated in Fig. P6.4-6a. Derive a formula that relates the value of the section modulus S to the number of planks used to make the beam. Assume that the thickness of each glue layer is negligible and that the laminated beam behaves like an ordinary wood beam. (b) A simply supported glulam beam of width b = 200 mm and length L = 5 m supports a concentrated load P = 9 kN at its center, as shown in Fig. P6.4-6b. The magnitude of the allowable stress of the wood in tension or compression is allow = 6 MPa. Determine the number of planks of thickness r = 50 mm required for the lightest glulam timber beam that can be used for this appli- cation. 22 nt 22

Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.
