INTRODUCTION
Generation of electricity by Speed breakers
An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. An energy crisis may be referred to as an oil crisis, petroleum crisis, energy shortage, electricity shortage electricity crisis The cause may be ageing over-consumption, infrastructure and sometimes bottlenecks at oil refineries and port facilities restrict fuel supply.. If this is correct it is also to blame. 2008 Central Asia energy crisis, caused by abnormally cold temperatures and low water levels in an area dependent on hydroelectric power • Solution for Energy Crisis NEXT time on the roads, don’t scoff at the speed-breakers
4.2 MECHANICAL DESIGN
Mechanical design phase is very important from the view designer. As success of the project depends on correct design analysis. Many preliminary alternatives are eliminated during this phase. Designer should have adequate knowledge above physical properties of material, loads stresses, deformation and failure. He should identify the external and internal forces acting o0n the machine parts.
These forces may be classified as:-
• Dead weight forces.
• Friction forces.
• Inertia forces.
• Centrifugal forces.
• Forces generated during power transmission, ets.
Designer should estimate these forces very accurately by using design equation.
Assumption must always be on the safer side. Selection of factors of safety to find working or design stress is another important step in design of working dimension of machine elements. The correction in the theoretical stress values are to be made according in the kind of loads, shape, of parts & service requirements.
Selection of material should make according to the condition of loading, shapes of products, environment condition & desirable properties of material. Provision should make to minimize friction by adopting proper lubrication methods.
