A composite rod with the same cross-sectional area over its entire length is composed of material, = "malleable cast iron" (segments AB and CD) and an unknown material (segment BC). Under the axial compressive loading shown, the change in length from point A to D is 8 = -8.46475 x 10 4. in . The material that segment BC is most likely composed of is: Consider compressive forces negative and tensile forces positive Lac-> LAB- LAB - 4.5.in LBC -...
Consider the rectangular prism shaped wire shown in the figure
below where the cross sectional part is a square with sides d=10.1
mm. The current runs along the length of the wire where ℓ =7.3 m
and the wire has cylindrical hole along its length with a cross
sectional area of A=21 mm2. If the wire is made out of a material
whose resistivity is 126 × 10-6Ω.m , determine the resistance of
the wire.
