Document Summary
Chapter 5 symmetric bending of beams (i) stresses. Beam is a slender component which supports transverse loads and its cross-sectional dimensions are small compared to the length. Types of loads on beams are described below: concentrated force. Transverse loads are applied a beam and then induce shear force and bending moment in the beam. Consider a cantilever beam subjected to a concentrated load at the free end and analyze the shear force and bending moment at the section 1-1, in terms of force equilibrium or free body diagram (fbd). In general, both shear force and bending moment vary along a beam (x coordinate) under loading. 5. 2. 1 sign convention for shear force and bending moment. There is no standard convention for shear force and bending moment, but the follow convention is popular. + m to make tension of the bottom part of the beam. M to make tension of the top part of the beam.
