If the beam is subjected to a shear of V=30kN determine the web's shear stress at A and B. Indicate the shear-stress components on a volume element located at these points. Set w = 125 mm. Show that the neutral axis is located at y = 0.1747 m 0.1747 m from the bottom and INA = 0.2182(10-³) m4. 30 mm 250 mm 30 mm 200 mm W -25 mm V B

If the applied force P is 3.6 kN, determine the maximum normal and shear stress at point A on the surface of the beam, respectively. B+ Ţ15 mm C: 30 mm 18781 30 mm 6 mm 0.4 m 0.4 m 6 mm

The beam has a square cross section and is made of wood having an allowable shear stress of Tallow= 1.4 ksi. If it is subjected to a shear of V= 1.5 kip, determine the smallest dimension a of its sides. Sketch the shear stress distribution acting across the beam's cross section. Hint: Construct the stress distribution in 2D similar to in-class examples, rather than isometrically similar to the textbook examples for clarity. V = 1.5 kip
