++++ ++++ ++++ ++++ ++++
For the potato-shaped body given in class to
explain the concept of stress, the ?eld of stress
vectors t
(n)
= t
(n)
(x) on the plane of normal
n given by its cartesian components (1, 0, 0) is
known and its cartesian components are given
by the expression:
t
1
= (10 MPa)x
2
; t
2
= 0; t
3
= 0
This information is enough to determine:
? a) the complete state of stress at point x
? b) all the stress components on any other
plane passing through point x,
? c) none of the stress components on any
plane, including the plane of normal n.
