It is first introduced here as an exact analytical method for finding the response of a single-DOF system. However, first we must define the unit impulse function. The unit impulse function If a force, F, acts on a mass, m, for time δt, we know from Newton's second law that the ...
laplace transformunit impulse functionDelta function is an important function in mathematics and physics. In this paper, the Laplace transforms of δ(t)and δ(t-τ)have been discussed in detail. After the Laplace transform of δ(t)is analyzed, the author has found that three aspects should ...
But the integral in the right-hand term is the Laplace transform of the function, x(t), before it was shifted; that is, the right-hand integral is just L[x(t)]. Hence the Laplace transform of the shifted function becomes: (6.18)L[x(t−T)]=e−sTL[x(t)] Equation 6.18 is th...
