Problem 1. Tourists like to take away "a slice of an antiquity", for example, from the Egyptian pyramids. Suppose an extreme cheap way to satisfy desires of tourists and to keep pyramids the whole.
 What standard should be used? Write the formula of the solution and offer idea of such solution.

Problem 2. Offer an idea of automatic system of protection of hydraulic engineering constructions from seismic and explosive shock waves. Any concussions are dangerous for a dam. Usually in water the wave which strongly can strike on a dam is formed. Imagine, that the powerful wave goes to a dam with the big speed. She(it) in 1 km from a dam, already 100 m … That should take place?
 What standard should be used? Write the formula of the solution and offer idea of such solution.

Problem 3. The filter from sintered ceramic powder represents the cylinder which should be soldered to an end face of a pipe. How usually they make the soldering? The cylinder put vertically, fill a powder of solder along the perimeter and press an end face of pipe from above. All this assembles with the help of special equipment and then the joint is entered into inductor. Solder melts and the inductor is switched off several seconds later. Disadvantage: the part of solder under action of capillary forces spreads along the direction to the centre of an end face of the cylinder, reducing the useful area of the filter.. How to be? Which standard should be used? Write the formula of the solution and offer idea of such solution.



Problem 4. In a cup (diameter D=1 cm)with about 1 ml of a biological nutritious solution are raised some biological objects (not important which kind). Process of their duplication and growth is studied. The cup is shined (covered) by a powerful light source and with the help of a micro-videocamera the image moves on the screen of a computer. The contradiction: objects should be shined well (covered), but at a close arrangement of a light source (a cathodic luminescent lamp, D=1 cm) is strongly heated up the solution and objects instantly dies. How to be?
Which standard should be used? Write the formula of the solution and offer idea of such decision.
