Question:
A Drake conductor with a diameter of 28 mm, a cross-section of 468 mm2, a weight of 1.62 kg/m, a modulus of elasticity of 9100 kg/mm2, a heat elongation coefficient of 19x10-6 1/ ̊C and maximum stress of 12 kg/mm2, was used on a conveyor line located in the third ice load region. Since the equivalent distance of the line is 160 m, the critical span is 76 m and the critical temperature is known as 21 ̊C, accepting the ice density as 0.8 gr/cm3 and using the equation of different states;
a) In the case of 86 km/h wind blowing on the normal zone ice at -5 ̊C
b) In the case of the lowest ambient temperature
Find the equations of the tensile forces.
