The rigid beam ACE is subjected to the load P and suspended at points A, C, and E
The rigid beam ACE is subjected to the load P and suspended at points A, C, and E by three suspender bars AB, CD, and EF (see Figure 1). These three suspender bars are made of the same steel and have the same circular cross section with the same diameter of d=30 mm. The ultimate 2m stress of steel is σu=450 MPa and Young modulus is E=200 GPa. (a) Using a factor of safety FS=1.5, determine the All maximum allowable load...
