A rigid bar ABCDE is hinged at end A and supported by three cables at points B and C and D Cable C has a nominal diameter of 12 mm and an area of 76.7 mm2, and an ultimate load of 102 KN. Cable B and D has a diameter of 20mm and an effective area of 173 mm2, and an ultimate load of 231 Kn. The cables have an effective modulus of elasticity 140 GPa and a thermal expansion coefficient of = 12 x 10-6 / ºC. A charge P acts at the end E of the bar. a) What is the allowable load P if the temperature increases by 60ºC and a safety factor of at least 5 is required against your ultimate charge? b) Determine the displacement of point E on the bar.

Transcribed Image Text:Arigidbar ABCDE is hinged at end A and
supported by three cables at points B and C and D
Cable C has a nominal diameter of 12 mm and an area of 76.7 mm2,
and an ultimate load of 102 KN.
Cable B and D has a diameter of 20mm and an effective area
of 173 mm2, andan ultimate load of 231 Kn.
The cables have an effective modulus of elasticity
140 GPa and athermal expansion coefficient of a = 12x10-6/ C!
A charge P acts at the end E of the bar.
a) What isthe allowableload Pif the temperatureincreases by 60 C
and a safety factor of at least 5 is required
againstyour ultimate charge?
b) Determine the displacement of point E on the bar.
