MOOC – “Mechanics of Materials III”
Section Four Quiz Solution
Problem 1) A cross section of a T-beam shown below is subjected to a constant shear
force of 4000 N. Assume the beam acts as a linear elastic material.
Solve for the transverse shear stress 100 mm from the bottom of the beam’s cross section.
Problem 2) A cross section of a T-beam shown below is subjected to a constant shear
force of 4000 N. Assume the beam acts as a linear elastic material.
Solve for the maximum transverse shear stress and its location.
Problem 3) A hollow wood beam cross section is subjected to a constant shear force of
25,000 N. Assume the beam acts as a linear elastic material.
Solve for the transverse shear stress 75 mm from the top of the beam’s cross section.
