The objective of the work was to evaluate contact fatigue and operating performance of electrodeposited Ni-WC composite coated gears using experimental technique. The electrodeposited Ni-WC coating was characterized for coating thickness, hardness and cry... see more

This paper reports the result of an investigation of a fatigue failure of a helical gear in a reducer gear box used in roller press milling machine. Standard procedures in stress analysis on helical gear were used in failure analysis of this helical gear.... see more

Purpose. In the research one should do: 1) to determine a 3-d stress-strain state of the rail head in contact with the rolling wheels; 2) to analyze different forms of contact interaction; 3) to obtain the data necessary to calculate the durability of rai... see more

Changes in oxygen cost per a given distance of running due to fatigue have often been accompanied with alterations in running kinematics. Nevertheless, it is not certain if the changes in the oxygen cost of transport are as a result of the fatigue or the ... see more

An automobile brake disc brought into contact with the pads, mechanical stresses are imposed on the contact surface. These stresses can cause degradation by fatigue, rupture, wear, propagation of cracks. Modeling the numerical results makes it possible to... see more

Introduction: Nurses have a very stressful job because they are required to deal with the needs of patients. Nurses are responsible for contacting and observing patients 24 hours a day. The nurse fatigue is associated with stress at work, workload, and th... see more

Introducion. In the nurse profession, contact with another person plays a very important role. In the work environment of nurses there are many factors that are a source of stress, are an increasingly serious problem for working nurses and affect the lev... see more

Steering agricultural machinery during the harvest in fields is a tedious task for drivers. Automated guidance of the machinery will not only reduce driver fatigue but also increase productivity and safety of the harvesting operation. The existing mechani... see more
