Problem 8-12 A bar of rectangular cross-section, with a width of 60 mm and a thickness of 40 mm, is bent in the shape of a horse shoe having a mean radius of 70 mm. Two equal and opposite forces of 10 kN each are applied at a distance of 12 cm from the centre line of the middle section so that they tend to straighten the rod. Find the maximum ten- sile and compressive stresses and construct a diagram showing the vari- ation of the normal stresses over the central section.

Problem 8.12 A bar of rectangular cross-section, with a width of
60 mm and a thickness of 40 mm, is bent in the shape of a horse shoe
having a mean radius of 70 mm. Two equal and opposite forces of 10 kN
each are applied at a distance of 12 cm from the centre line of the middle
section so that they tend to straighten the rod. Find the maximum ten-
sile and compressive stresses and construct a diagram showing the vari-
ation of the normal stresses over the central section.
