One of the most fundamental relations governing the dynamic properties of materials is Hooke's law of elasticity. Hooke's law is a relationship between stress and strain. Hooke's law describes materials which have relatively low damping very accurately. Short theory needed for calculation of elastic modulus, shear modulus and Poison's ratio is presented in this paper. Static measurement stress-strain characteristics of rubber and dynamic tests were described. Calculation of elastic modulus, shear modulus and Poisson's ratio of rubber is shown. Then the influence of strain' velocity on elastic modulus was measured and calculated and complex elastic modulus was calculated from dynamic tests.

The article is dealing with the measurement of the tire impurities circulation by the dynamic loading along with the disc. There are made measurements for the various tire velocities on the roadway by the constant inflation pressure in tire and by the tire constant external loading and time service longitudes. In the article is suggested the process of the measurement evaluation by the method of the active factor experiment.

A building line is a common type of equipment used in the rubber-processing industry to build radial truck tyres in the semi-automatic production mode. The bearing-type transferring is part of the equipment. The paper presents an analysis of the load exerted on the bearing-type transferring depending on its fixation at the top of the frame. The paper also presents results of the stress and frequency analysis of the transferring.
