- MSDs complaints generally include the muscles of neck, shoulders, arms, hands, fingers, back, waist and lower muscles. Activities carried out by workers that have been going on for a long time such as repetition, force or pressure, vibration, and/or awkward positions are cause musculoskeletal disorders. This research method uses quantitative with cross sectional approach. The was conducted in...

The article presents the results of research on influence pressure in car tires braking distance. Tires with lower than nominal pressure, higher and for comparison were analyzed. tests carried out a bituminous surface typical most road surfaces Poland. Six dry surface, wet covered snow. cars equipped sets summer winter tires. tire distance was two practically identical very similar curb weight ...

In this study, a low degree-of-freedom mechanical model of a rolling tire is constructed, in which the lateral deformation of the contact patch and tire carcass is considered. The so-called delayed contact patch model is implemented and combined with a simple tire carcass model. The interaction between the contact patch and the carcass together with the lateral mode of the attached suspension s...

The article informs about the current development of raw materials needed for production tires, while its main goal is to acquaint and warn readers inappropriate choice preference all -season tires. all-season tires their over standard footwear often chosen by car users, mainly because financial savings. At present, this type can be other drivers due shortage tire production. Therefore, intenti...

Scrap tires continue to be a major source of waste due to the lack of valuable and effective disposal routes. A viable solution to this problem is to recycle crumb rubber (CR)-a granulated material derived from scrap tires-and use it to develop other valuable products. Herein we report the fabrication and characterization of CR-modified coatings with anticorrosive properties on metal substrates...

In the early 1900s, the Ford Motor Company would not have known what a T1 line was. If somebody had suggested to the senior managers at Ford that a T1 line would one day have something to do with who would manufacture the tires on Ford’s cars, they would have been shown the door – for this was a time when the Ford Motor Company bought a rubber plantation in order to control the production of ti...

The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented. An example calculation of rolling resistance for a polyurethane tire is giv...
