Creаte 5 vаriаtiоns оf the fоllowing problem but do not show the answers. At a point subjected to plane stress on the surface of a backhoe, the stresses are σx = –100 MPa, σy = 30 MPa, and τxy = 80 MPa. Determine the angle θp corresponding to the orientation of the principal planes at the point.
Creаte 5 vаriаtiоns оf the fоllowing problem but do not show the answers. At a point on the free surface of a steel automotive component [E = 28,100 ksi,ν = 0.15], a strain rosette was used to obtain normal strains of εa = 340 με, εb = –290 με, and εc = 10 με. Determine normal strain εx at the point.
Creаte 5 vаriаtiоns оf the fоllowing problem but do not show the answers. At a point subjected to plane stress on the surface of a structural member, the stresses are σx = 17 ksi, σy = 18 ksi, and τxy = –8 ksi. Determine the magnitude of the absolute maximum shear stress at the point.
