WHY DON’T BUILDINGS FALL?


 


Why don’t buildings fall?
Since the dawn of time man has constructed spaces to protect himself, his family, and his livestock. Originally he made use of natural spaces. Later he applied his accumulated knowledge to whatever materials were available. Structures are built for different purposes: buildings – to define space; bridges – to link two points; reservoirs – to contain materials. In the course of time man has learned to process materials and elements and utilize them as efficiently as possible. Today a wide range of materials are employed for this purpose: concrete, wood, steel, aluminum, plastic and so on.
Architects and town planners make use of models to demonstrate three- dimensional structures and examine whether their height is compatible with their surroundings. These models are sometimes computerized. Engineers also employ computerized models to test durability under extreme conditions.
In this exhibit visitors are presented with challenges and invited to build models and locate the strength of materials. Knowledge of basic scientific principles facilitates intuition and helps solve everyday problems. For example: How should you put up a ladder? How thick must a rope be to hoist a pail of water from a well? And how would you use a tent cloth, pegs and ropes to put up a tent on the seashore?
