Question

A point in body is in a state of plane stress. The applied direct stress on the face, with normal parallel to the X axis, is 65 MPa with an unknown applied shear stress on the same face. NB - Tensile direct stresses are +ve, Compressive direct stresses are -ve. The maximum in plane shear stress is 111 MPa. The direct stress, on the plane corresponding to maximum shear stress, is 28 MPa. You must use a diagram to illustrate your working, but may use either calculations or precise, scaled diagrams to find the values.

NB round all answers to one decimal place for the given units.

a) Determine the principal stresses

Calculate the answer -------------------. MPa - NB this entry must be the larger value

-Calculate the answer -----------------------. MPa - NB this entry must be the smaller value

b) Determine the magnitude of the applied shear stress on the face with normal parallel to the X-axis

-Calculate the answer ------------------------------ MPa
