10. Galileo Galilei

11. Galilei’s experiments Galilei was the first person who found out that heavy objects fall from the height with the same speed as the light ones. To prove the hypothesis he threw two objects (80 kg and 200 gm) from the Tower of Pisa. Both objects had streamline contour. They reached the ground simultaneously.

13. Problems:
1. Evaluate the free fall acceleration. And remember the value of this constant. (h = gt² /2 ) 2. Evaluate the time of fall of an object from the height of 60 m. 3. How many tourists can be inside the Tower of Pisa at one and the same time not to make it falling? (α = 3˚30’; h = 56,7 m; q = 2,6 MN/m; Fper = 800 N; Mmax = 25 MNm)

14. Nevyansk Tower, Sverdlovsky region
