Chapter 15 - Combined Loading

 

by Derek Fryar, 2000

 

	axial		σ = N/A
	torsion		τ = Tc/J
	flexure		σ = -My/I
	shear		τ = VQ/Ib
	pressure		σ = pr/t & pr/2t
	combined		σ = Σσi τ = Στi

homework

1. shafts:  axial (N/A) + torsion (Tc/J)
2. beams:  flexure (My/I) + shear (VQ/Ib)
3. posts:  everything
   • σ = N/A + My/I + pr/2t
   • τ = Tc/J + VQ/Ib
