It may be assumed that a body consists of small particles or molecules, between which forces are acting. These molecular forces resist the change in the form of the body which external forces tend to produce. If such external forces are applied to the body, its particles are displaced and the mutual displacements continue until equilibrium is established between the external and internal forces. It is said in such a case that the body is in a state of deformation or strain. During deformation the external forces acting upon the body do work, and this work is transformed completely or partially into the potential energy of strain. An example of such an accumulation of potential energy in a strained body is the case of a watch spring. If the forces which produced the deformation of the body are now gradually diminished, the body returns wholly or partly to its original shape and during this reversed deformation the potential energy of strain, accumulated in the body, may be recovered in the form of external work.

There are not so many companies in the world, which have the rules of control system usage. It is quite clear, that a skilled manager, using his own experience, applies principles of management style variation. However, it is rather dangerous to make a manager the only one responsible for it, as it has often caused the crash of many companies. The manager accepts a wrong decision, and using the authoritative principle, forces the whole company’s structure to work accordingly (“They misunderstood me, so they made it all wrong” – how often we hear it). On the other hand, if we use the consensus principle, a sluggish decision-making can provoke an effect of delay. In this case no one will be responsible for the company’s crash – it will be regarded as a bad destiny. It is necessary to mention that while creating management algorithms it is important to determine the management concepts accepted in the company, i.e. one staff member can understand something well, while for another one it may be so apparent.

Machu Picchu
1. Set high in the Peruvian Andes, the ruins of the Inca city of Machu Picchu are among the world’s most magnetic tourist sights. Until recently reaching this mountain aerie meant a long, heart-pounding trek led by local guides. Today, globetrotting tourists arrive with nonchalant ease in air-conditioned comfort. Spanish colonialists, the collapse of high Incan culture, the elements, and natural calamities have done their best to wipe the historic architecture of Peru off the map.
2. The remote and haunting remains of Machu Picchu, however, allow us to see the great, rigid power of Inca architecture at its best and most daunting. The site of this powerful walled city, lying between two mountain peaks some 3,000 ft (900 m) above the Urubamba River, was a revered place long before the Incas began to build here with real purpose in about 1400. Inside the well-cut gray granite walls are the remains of a wide range of public buildings including palaces, baths, temples, storehouses, and burial grounds.
3. There are about 150 houses, gathered in groups around communal courtyards and aligned in terraces. The various parts of the city, on their complex series of terraces, were connected by grand stone stairs. One of the important remains found at Machu Picchu is the Intihuatana stone, used in an astronomical ritual for “tying” the sun to the earth at the midday equinox, in the perpetually vain hope of slowing its movement across the sky.

Hurricane preparation tips for construction sites
1. Local emergency operations officials and the National Weather Service will provide hurricane landfall probabilities. Approximately 60 to 48 hours before the hurricane is expected to make landfall, consider cancelling the delivery of building materials to all job sites except any materials needed to secure the building site from storm damage. While contractors generally don't want to stop or delay construction activities, the 48- to 24-hour window before landfall is the suggested time to stop all construction activity. It's important to note that most local building departments generally stop field inspections, except for those related to pouring columns, tie beams, wet decks, floors and similar structural items, during this time as well. Contractors are encouraged to activate their hurricane job site plan during this window of time.
2. They notify subcontractors to help secure the building site. Helpful hints for site protection include: secure all job sites, giving priority attention to those located in the most populated areas; clean up all construction debris; tie or band together all loose plywood and lumber; secure other loose building supplies; remove permit board and all job site signage; locate and turn off electricity, water and gas.
3. Also, secure all portable toilets. Portable toilets can also be anchored adjacent to L-shaped walls of the home under construction and they can be weighted down with concrete blocks or sand. After the site is secure, advise subcontractors to leave and not return until the hurricane threat has passed. Make sure to have contact numbers for all subcontractors stored in a secure and dry place and that they know who will contact them after the hurricane passes.
