QUESTION 1
An element in plane stress is subjected to stresses; Ox, Oy, and Txy (FIGURE 1). Using
Mohr's circle, determine the stresses acting on an element oriented at an angle 0 from the x
axis. (Note: The angle 0 is positive when counter clockwise and negative when clockwise.)
i.
Normal Stress (ox', oy')
ii.
Normal Shear Stress ( T x'y')
iii.
Maximum and Minimum Stress (01, 02)
iv.
Maximum Shear Stress (Tmax )
V.
Show the Main stresses on a sketch of an element oriented and maximum shear
stress oriented.
Ox = -40 MPa
Oy = 50 MPa
Txy = -60 MPa
