Calculate the natural frequency of vibrations. Check if the resonance phenomenon occurs. Determine the amplitudes of deflection and inertia forces occurring in the given frame system. The frequency of the excitation force is 𝑓𝑣 =5𝐻𝑧, and its maximum value is 𝑃 =100𝑁. The data is 𝐸 =210𝐺𝑃𝑎,𝐼 =10𝑐𝑚4,𝑚 =10𝑘𝑔.
