An overhead signal has a mass of 45 kg. It is supported on a 1.5 m cross ba made from round tube of 50 x 2 mm which is welded to a 3 m vertical rour pole made from 76 x 2 mm round tube. Using the loading indicated, calculate the: (a) vertical displacement of the signal when exposed to the wind. (b) angle at which the signal will hang it mounted perpendicular to cross beam.

An overhead signal has a mass of 45 kg, It is supported on a 1.5 m Cross bar
made from round tube of 50 x 2 mm which is welded to a 3 m vertical round
pole made from 76 x 2 mm round tube. Using the loading indicated,
calculate the:
(a) vertical displacement of the signal when exposed to the wind.
(b) angle at which the signal will hang it mounted perpendicular to cross
beam.

Assume the tubing to be made from a material with Young's
Modulus 200 GPa, Shear Modulus
0.29, Yield Strength 215 MPa, Tensile Strength = 505 MPa,
Density = 8000 kg/m. Using the loading indicated calculate the
vertical displacement of the cross bar end when the signal is
M=45 kg
= 86 GPa, Poisson's Ratio =
mounted.
Expert Solution
Step 1
The vertical displacement of the signal when exposed to the wind =280mts
The angle at which the signal will hang it mounted perpendicular to cross beam= 1100
