The 'Trif' calculation is intended to equate to the percentage of workers we hurt per year (within a specific population, such as company or industry).

Since the average person works about 2000 hours per year, and in order to get a percentage, we must multiply by 100, we come up with the equation:

200,000 X Number of 'recordable' incidents divided by total man hours actually worked.

Finding natural frequency of a simple pendulum by energy method?

Energy methodIt is possible to calculate the frequency of different mode shapes of system manually by the energy method. For a given mode shape of a multiple degree of freedom system you can find an "equivalent" mass, stiffness and applied force for a single degree of freedom system. For simple structures the basic mode shapes can be found by inspection, but it is not a conservative method. Rayleigh's principle states: "The frequency ω of an arbitrary mode of vibration, calculated by the energy method, is always greater than - or equal to - the fundamental frequency ωn."For an assumed mode shape , of a structural system with mass, M; stiffness, EI (Young's modulus, E, multiplied by the second moment of area, I); and applied force, F(x):then, as above:
