ME 212 STRENGTH OF MATERIALS
QUESTION # 1 (DÖÇ-3,5) 50p
For the cantilever beam given in the figure,
a) Determine the state of stresses at points A and B.
b) Show these state of stresses on cubic elements taken
from these points.
c) Determine the principle stresses at point B by using
Mohr's circle. Calculate the oriantation of the
principle stresses and show the results on a cubic
element.
d) Determine the max. in-plane shear stress at point A
by using Mohr's circle. Calculate the oriantation of
the max. in-plane shear stress and show the results
on a cubic element.
Note: Solution should include the parts "internal
loadings", "section properties", "stress components"
Given:
- P, R and Q
- a, b, c, d, and l
Data P (kN) R (kN) Q (kN) a (mm) b (mm) c (mm) d(mm) l (mm)
