a) The state of stress at a point is shown on the element in Figure Q4(a) Deternine i) The principal stresses (in-plane) and the corresponding principal planes; 1) The maximum in-plane shear stress and the orientation of the corresponding plane as well as the normal stress on that plane. 60 MPa 30 MPa 45 MPa Figure Q4(a)
1.) Consider a stress block in a state of pure shear as shown. Tx Derive the 2-D stress transformation equations (Og & ??) for face (A)if it is rotated an angle of ? counterclockwise from the vertical. 2.) Sketch the 2-D Mohr's circles for each of the stress blocks shown below and evaluate ?1, ?2, and ?max for each. All stresses are in ksi. 6 5
Stresses at a point are: Only shear stress of -40 MPa (Pure Shear). What are the stresses at 45o clockwise? Identify the principal stresses and show them on a properly-oriented element. Mohr’c cirle is to be used and no equations will be accepted.
The state of stress at a point is shown on the element. Determine (a) the stress components acting on the inclined plane AB, (b) the principal stresses, and (c) the maximum in-plane shear stress and average normal stress at the point. Specify the orientation of the element in each case. Sketch the results on each element. 2 ksi 3 ksi 30° 4 ksi
