Unformatted text preview: direction without shear stress Maximum shear stresses • Similarly there exists a maximum shear stress τ m as well • Tangents tan2 α s and tan2 α p is negative reciprocals • The difference between α s and α p is π /4 • m occur when normal stresses are equal • However, σ 1 and σ 2 relative to m (i.e. at α = α s ) are not necessarily be zero • m = | σ 1-σ 2 |/2...
