Задача 10883.

What is the moment of inertia of the pendulum Oberbeck if a weight of 790 g dropped at an average speed of 0.15 m / s during the 11? 23 mm radius pulley; acceleration due to gravity take equal 9.81 m / s <sup> 2 </ sup>. How many times will decrease the moment of inertia of the pendulum Oberbeck if goods move from the ends of the rods to the middle? The mass of each weight 145 g, length 0.3 m rods. <br>

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
