Fig shows a bar of uniform cross section of area `s`. Equal and opposite tensile forces are applied at the ends of the bar. Each force has a magnitude `F`. ABCD is a plane trough the bar and inclined at angle `theta` with the perpendicular to the length of the bar.

Shear stress on the inclined plane will be maximum for `theta=`
