- 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.
- Normalise a student enrolment table to 3NF
3NF removes repeating groups, partial and transitive dependencies. The result is separate Students, Modules, Tutors and Enrolments tables.
- 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.
