A 1750 N irregular beam is hanging horizontally by its ends from the ceiling by two vertical wires (A and B), each 1.25 m long and weighing 0.290 N. The center of gravity of this beam is one-third of the way along the beam from the end where wire A is attached. If you pluck both strings at the same time at the beam, what is the time delay between the arrival of the two pulses at the ceiling? Which pulse arrives first? (Ignore the effect of the weight of the wires on the tension in the wires.)

Question
A 1750 N irregular beam is hanging horizontally by its ends
from the ceiling by two vertical wires (A and B), each 1.25 m long and
weighing 0.290 N. The center of gravity of this beam is one-third of the
way along the beam from the end where wire A is attached. If you pluck
both strings at the same time at the beam, what is the time delay between
the arrival of the two pulses at the ceiling? Which pulse arrives first? (Ignore
the effect of the weight of the wires on the tension in the wires.)
