In this paper, an example of separation of a planar beam on which an impulse of impact force acts is analyzed. Applying the suggested equations, velocity and angular velocity of the remainder beam are determined

The impulse acting on the material is equal to the momentum increase of the material during the instantaneous relief stage. Because the material cell is assumed to be a ball, on which the pressure is described as below: (6.31)σ=P3−Paπd2 (6.32)P3−Paπd2×t=ms⋅v2where t is ...

Policy-makers should always try to ally with this impulse toward self-protection. They should try to guide it away from precautions that are actually harmful to oneself or others (or the economy). But they should not oppose it or belittle it. In addition, I conclude, research, education, ...

We present a numerical method derived from the Impulse-Linear Momentum Principle that can be used in the design of impact tools for rock drilling. This method allows the prediction of energy transmission to rock, the profiles of stress, displacement and velocity, all of which are important in ...
