Why are the ripple absent in the synthesis of the periodic train of triangle pulse?

Why do you observe ripples in the synthesis of the periodic train of square pulse?

Consider the steel column of a single storey building with the system of parallel forces as

shown in the Fig. Determine the magnitude of FA and FB such that the resultant force passes

through origin O of the given column. Use only vector approach to solve the unknowns

given.

What is the effect of varying the number of samples and the frequency as in the steps (7) and (8), respectively?

How the number of ripples is related to the number of harmonics in the

synthesis of the periodic train of square pulse?

Find the spectral components of a periodic train of a square pulse with an even symmetry by applying Fourier series analysis. Consider the period of 1 s for the repetition of the square pulse.

A system of forces 340 N, 760 N, 800 N, 600 N, 700 N and 500 N (in order) acting on

900 mm by 400 mm plate (with negligible thickness) is shown. Find the resultants with

respect to O.
