Question

5. The stresses on two perpendicular planes through a point in a body are 30 MPa and 15 MPa, both tensile along with a shear stress of 25 MPa. Find (i) the magnitude and direction of principal stresses (ii) The planes of maximum shear stress (iii) the normal and shear stresses on the planes of maximum shearing stress.

​

Answer 1

Answer:

Maximum shear stress and principle stress is given by,

Calculation:

σx = 120 MPa (T)

σy = 60 MPa (T)

τxy = 30 MPa

Let σ1 and σ2 are principal stresses.

We know that

σ1 = 132.43 MPa (Tensile)

σ2 = 47.57 MPa (Tensile)

Answer 2

Answer:

σx = 120 MPa (T)

σy = 60 MPa (T)

τxy = 30 MPa

Let σ1 and σ2 are principal stresses.

We know that

σ1 = 132.43 MPa (Tensile)

σ2 = 47.57 MPa (Tensile)
