Question:
The lower end of a homogeneous beam of mass kg is attached to a wall by means
of a frictionless hinge. The beam is kept in balance by a horizontal cable
is attached to the top end so that the beam forms an angle of degree with the wall. The cable
has a length of m and a mass of kg The speed of sound is ms
a Determine the cable tension and the reaction force in the hinge.
b What is the fundamental frequency of transverse standing waves on the cable?
c What is the frequency and wavelength of the sound produced by the cable vibrating at the fundamental frequency?
