Rocker arms are part of the valve-actuating mechanism. A rocker arm is designed to pivot on a pivot pin or shaft that is secured to a bracket. The bracket is mounted on the cylinder head. One end of a rocker arm is in contact with the top of the valve stem, and the other end is actuated by the camshaft. In installations where the camshaft is located below the cylinder head, the rocker arms are actuated by pushrods. The lifters have rollers which are forced by the valve springs to follow the profiles of the cams. Failure of rocker arm is a measure concern as it is one of the important components of push rod IC engines.Present work finds the various stresses under extreme load condition. For this we are modeling the arm using design software and the stressed regions are found out usingAnsys software. Here in this thesis we are observing that by changing different materials how the stresses are varying in the rocker arm under extreme load condition. And after comparing results we are proposing best suitable material for the rocker arm under extreme load conditions.

Keywords: Ansys, camshaft, pro-e and rocker arm

A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power. Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft. Superchargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. Here in this project we are designing the compressor wheel by using Pro-E and doing analysis by using FEA package. An attempt has been made to investigate the effect of pressure and induced stresses on the blade. By identifying the true design feature, the extended service life and long term stability is assured. A structural analysis has been carried out to investigate the stresses, strains and displacements of the blade. An attempt is also made to suggest the best material for an blade of a turbocharger by comparing the results obtained for different materials. Based on the results best material is recommended for the blade of a turbocharger.

The South Eastern part of Nigeria was a single state of the twelve states of Nigeria before 1976 – East Central State. Presently, the area is made up of five states. This Paper presents a study carried out to assess the possibility of knitting the once-one-state and presently five states, together to form a tourist destination worthy of international importance. Although the unprecedented dearth of infrastructural development in the zone continues to be a subject of discussion, little attention has been given to investigate the place of synergized intervention. Descriptive analysis was employed, in which the tourism potentials in the zone that are of national recognition were itemized. Data were collected on available amenities, resident population and accessibility of such potentials. Existing literature on various Environmental Management Systems were explored to elicit a system that is capable of affording a sustainable environment for tourism matters in the zone. The study revealed that the zone exhibits similar socio-economic and physical characteristics that are replete with potentials for improvement for optimum tourism utility in the entire zone. Several measures were advanced in the study to achieve this, chief of which is the adoption of the Environmental Planning and Management (EPM) process.

Keywords: Tourism destination, national significance, tourism potentials, EPM-process.
