Let us consider that σ 1, σ 2 and σ 3 are the ,principle, stresses at a point in material and σ t is the ,principle stress, in simple tension at elastic limit. Now as we know that maximum shear ,stress, at a point in the material will be equal to the half of difference between maximum and minimum ,principle stress, and therefore we will have following equation.
This ,helmet, is REPLACING a ,helmet, that has already scored a ,5,-star SHARP rating — and this newer, improved version is no different, scoring ,five, stars of its own. Like the IS17, the C70 is a polycarbonate shell included with a drop-down sun visor, micrometric fastener, and easy-release main visor.
