• ###### (PDF) Energy transfer ratio of hydraulic pile driving hammers

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F avg = (800 ft lb) / (0.0625 ft ...

• ###### Energy of falling object - HyperPhysics Concepts

The aim of this study is to estimate the impact loads delivered to the housing of a hydraulic breaker quantitatively. Striking forces caused vibrations in the equipment housing, which were experimentally measured, and frequency response functions were also found through modal impact experiments. Transfer path analysis (TPA) method of the data quantified the impact loads delivered to the housing.
