Задача 10881.

What is the moment of inertia of the pendulum Oberbeck if weighing 785 g load falls from a height of 1.5 meters with a time of 10.5? pulley radius of 23 mm. Acceleration of gravity taken equal 9.81 m / s ^ 2. How many times will decrease the moment of inertia of the pendulum, if the loads weighing 145 g each move with the rod ends to the center, setting them at a distance (2l / 3) from the center? rod length 0.3 m.

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.
