Homework Statement
An example in my problem set (homework help) An oak rod is hung from a rigid support.
The rod has a diameter = 12 mm, length = 9 m, and a catch plate at its base.
a) The maximum mass of a weight that each rod can support.
b) The minimum mass of a weight that will break the rod when dropped from the top of the rod.
Numbers I think can be used: E (stiffness) = 14000 MPa
Yield Tensile strength = 75 MPa
Ultimate tensile strength = 90 MPa
