D-2-4 How does the Normal Force on the Rigid Rod Behave during Falling?(General Session in English (2))

抄録

In our previous studies, we investigated the friction which acts on a rigid body during falling before colliding with a floor. In the next step, we want to know how the normal force behaves during falling. As is well known, the maximum static friction depends on the normal force. Therefore, it is important to know the behavior of the normal force for the purpose of researching how the friction acts on the rigid rod. After this study will be completed,, we will investigate what condition will give rise to sliding or floating in falling.
