Problem 10. a) Find general solution of the oscillator under the periodic impulsive load represented by its Fourier series: 3 +wy = P(-1)+1 sin (2k-1)πt 2a P = const. k=1 b) Using appropriate slides from Chapter 11, draw a sketch of the load c) Assuming a fixed, determine the oscillator frequency values for which the resonance will take place.
