- Find the resonant frequency of a series RLC circuit
Resonant frequency is 1/(2π√LC), about 159 Hz. The quality factor is about 5 and bandwidth about 32 Hz.
- Calculate maximum bending stress in a simply supported beam
Maximum moment for a UDL is wL²/8 = 45 kNm. Dividing by the section modulus gives about 112.5 MPa.
