The thesis manly focused on the optimization of leaf spring lead to reduce stress. A leaf spring is a simple form of spring, generally used for the suspension system. Mostly the comfortably and life span of the parts of a ...

The most well-known aramid fiber is Kevlar, the lightest of any fiber reinforcement has high tensile strength for its weight, and is very tough. It is slightly less expensive than carbon fiber. And Kevlar/epoxy composite ...

Polymer Composites are now being used in engineering industries for light weight and low cost, at the same time as an inevitable behavior of material which provides sufficient stiffness under various load conditions. But ...

Spur gear is machine element which is subjected to cyclic loading must be designed against fatigue. Spur gear failure is caused by crack is which depends on cause of design and operation condition. The main objective of ...

The application of natural fibers could be enhanced by using them together with synthetic fibers which can potentially reduce the cost of the hybrid composites. This work presents an experimental study of mechanical ...

This research focuses on the mechanical properties of solid and hollow bamboo found in Ethiopian. The strengths of bamboo for different loading conditions were tested and characterized with respect to its age, culm position ...

The Ethiopian Arda plough is the most commonly used farm tool implement in Ethiopia. Nevertheless, using this plough as farm tool is labour intensive, time taking, shallow depth and narrow cutting width. Despite, the efforts ...

Leaf spring is widely used in automobiles and also one of the components of suspension system. It needs to have excellent fatigue life and less weight. As a general rule, the leaf spring must be regarded as a safety component ...

Micro-hydro power is considered as one of the most abundant sources of electrical energy throughout the world. It is renewable, environmentally friendly and less expensive which can be used for vulnerable communities ...

Crane hook is a vital component in the loading-unloading phenomena. Accumulation of massive amount of stress on crane hook due to repetitive loading unloading circumstance on the main hook of a crane, corrosion, ...
