Question
Textbook: Strength of Materials
Please provide step by step solution.
A formula sheet is provided for your reference.

Transcribed Image Text:The cross section of a beam is shown below. The formula for the Moment of Inertia
about the x-axis at the centroid of the section is shown below.
Outer Diameter = 50 mm
Inner Diameter = 40 mm
Ixc = (douter - dinner)
dinmer)
64
a) Solve for the moment of inertia, about the x-axis at the centroid.
b) Using the parallel axis theorem, solve for the moment of inertia, about the x-axis at
the top of the shape.
