An overhead signal has a mass of 45 kg. When exposed to a frontal wind it is exposed to a force of 540N. It is supported on a 1.5m cross bar made from round tube of 76 x 2 mm which is welded to a 3m vertical round pole made of 100 x 2 mm round tube. Assume the pipe to be made from a material with Young's Modulus = 200 GPa, Shear Modulus = 86 GPa, Poisson's Ratio = 0.29, Yield Strength = 215 MPa, Tensile Strength = 505 MPa, Density = 8000 kg/m3. Using the loading indicated calculate: (a) the stress condition at Point B (b) the principle stresses at Point B 0008

Please help with my homework and write clearly so I can see

1500 An overhead signal has a mass of 45 kg. When exposed to a frontal wind it is exposed to a force of 540N. It is supported on a 1.5m cross bar made from round tube of 76 x 2 mm which is welded to a 3m vertical round pole made of 100 x 2 mm round tube. Assume the pipe to be made from a material with Young's Modulus = 200 GPa, Shear Modulus = 86 GPa, Poisson's Ratio = 0.29, Yield Strength = 215 MPa, Tensile Strength = 505 MPa, Density = 8000 kg/m³. Using the loading indicated calculate: E= 540 N M = 45 kg (a) the stress condition at Point B (b) the principle stresses at Point B (d) the horizontal displacement of the signal when exposed to the wind. 0008
