A wood beam 1.8 m long is simply supported at its ends, has a cross-section 15cm wide by 60cm
deep and carries a uniformly distributed load of intensity w = 8000 kg/m over the full span.
Calculate the bending stress at a point 20cm above the bottom of the beam and 60cm from the
left support & also find out the maximum bending stress for this beam.
