初等刚体动力学中直觉的失效

Failure of intuition in elementary rigid body dynamics

Nivaldo A. Lemos

摘要:

假设一个抛射体垂直地撞击光滑水平桌面上的一个静止的刚性杆。我们表明,与人们自然期望的相反,它并不总是这样的情况下,杆获得最大角速度时,在一个极端打击。治疗的目的是为一年级的大学生的物理或工程,并可能形成的基础上,在刚体动力学守恒定律的教程讨论。

英文摘要:

Suppose a projectile collides perpendicularly with a stationary rigid rod on a smooth horizontal table. We show that, contrary to what one naturally expects, it is not always the case that the rod acquires maximum angular velocity when struck at an extremity. The treatment is intended for first year university students of Physics or Engineering, and could form the basis of a tutorial discussion of conservation laws in rigid body dynamics.
