Question

,5-16 A rigid bar ABCD is pinned at end A and supported by two cables at points Band C. The cables at B has a nominal diameter d& = 12 mm and the cablealChas a

nominal diameter Jτ = 20 mm. A load P acts at end D of the bar. 

What is the allowable load P i fthe temprature rises by 60°C and each cable is required to have a factor of safety of atleast 5against its ultimate load?

Note: The cables have an effiecent modulus of elasticity E = 140 GPa and coefficient of thermal expansion a = 12X10/°C. Other properties of the cables can be found in Section 2.2.
