Sažetak
An expression for the mathematical description of the shearing stress - shearing strain diagram in the form of the odd polynomials of the n-th order has been proposed. Particularly, application of polynomial of the third order was successful. Equations among shearing stress, shearing strain, twisting rate and twisting moment have been derived. The new concept of polar moment of inertia and section modulus of the fourth order have been introduced. They are calculated for an annular and a solid circular cross section. Finally a dimensionless diagram representing twisting moments as functions of twisting rate for different diameter ratios are given. By using this diagram shearing stress and shearing strain can be easily determined.
