this is achieved by controlled weakening of sacrificial outer parts of the car‚ while strengthening and increasing the rigidity of the inner part of the body of the car‚ making the passenger cabin into a ’safety cell ’‚ by using more reinforcing beams and higher strength steels. Impact energy that does reach the ’safety cell ’‚ is spread over as wide an area as possible to reduce its deformation. The crumple zone was originally made by an inventor called Bela Barenyi who came to the conclusion

Experimental parameters were: axial load ratio (0.15‚ 0.3 and 0.5) and width-to-thickness ratio (21‚39 and

Suspension bridge – A parabola What is meant by suspension bridge? A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. Outside Tibet and Bhutan‚ where the first examples of this type of bridge were built in the 15th century‚ this type of bridge dates from the early 19th century. Bridges without vertical suspenders have a long history in many mountainous parts of the world. Structure of suspension bridge

The First laser was developed in the 1970’s. A laser beam is generated in a glass tube with one side having perfect mirror and and the other having semi reflecting mirror. One of the mirrors is full reflective‚ and the other reflective 70% . The laser gas can be a mixture of He‚ CO2 and N2. This mixture of

Objects do not give out light by themselves are called __non-luminous_______ objects. Light consists of narrow rays travelling in __straight________ lines. A light beam is a stream of light.

the added strength‚ truss also do this without much additional weight. These concepts combined allow for trusses to be a very efficient way of adding strength. A cantilevered beam is what of which is supported on one end (usually a fixed support) and end is left hanging on the other end (Hibbeler‚ 2014). Cantilevered beams are able to support a load on the free-end. Cantilever trusses are popular in bridge and building architecture and possess many different uses. A cantilever truss with only a fixed
