A rectangular cross section at a location along a beam in bending is
(a). A rectangular cross section at a location along a beam in bending is acted upon by a bending moment and a shear force. The cross section is \(120 \mathrm{~mm}\) wide, \(300 \mathrm{~mm}\) deep and is orientated such that it is in bending about its major axis of bending. The magnitudes of the bending moment and shear force are \(315 \mathrm{kNm}\) and \(240 \mathrm{kN}\) respectively. Determine the maximum bending and shear stresses on the cross section. Plot the bending and...

The cross-section of an idealized I-section beam has overall dimensions 120 mm x 240 mm deep. If the web and flange are both 25 mm thick, determine the second moment of area of the section. If the maximum bending stress is limited to 100 MN/m2, determine the maximum load the cross-section can support at mid-span when it is used as a beam 2.5 m long and simply supported at the ends.

Problem 1 A simply supported beam of length L = 5m is subjected to a point load P= 20 kN at the mid span. Draw the shear force and bending moment diagram for the beam. If the beam is 300mm x 500mm, calculate the deflection at the midspan for the following orientations where the dashed line shows the bending axis. Explain the difference in results. Which orientation is better for beam performance and why? Take E = 30,000 MPa 300...
