A rectangular bar of length L has a slot in the central half of its length. The bar has width b, thickness t, and elastic modulus E. The slot has width b/3. If L = 400 mm, b = 51 mm, t = 11 mm, and E...

Extracted text: A rectangular bar of length L has a slot in the central half of its length. The bar has width b, thickness t, and elastic modulus E. The slot has width b/3. If L = 400 mm, b = 51 mm, t = 11 mm, and E = 64 GPa, determine the overall elongation of the bar for an axial force of P = 32 kN. b Answer: i mm
