Potential energy, π = _________
a) \(\frac{1}{2}\)QTKQ-QTF
b) QKQ-QF
c) \(\frac{1}{2}\)KQ-QF
d) \(\frac{1}{2}\)QF
Answer: a
Explanation: Minimum potential energy theorem states that “Of all possible displacements that satisfy the boundary conditions of a structural system, those corresponding to equilibrium configurations make the total potential energy assume a minimum value.”
Potential energy π=\(\frac{1}{2}\)QTKQ-QTF
