The maximum shear stress, in MPa at that point is _______.0 AnswerThe state of stress at a point in a component is represented by a Mohr’s circle of radius 100 MPa centered at 200 MPa on the normal stress axis. On a plane passing through the same point, the normal stress is 260 MPa. The magnitude of the shear stress on the same plane at the same point is ______ MPa.0 AnswerIf 1 and 3 are the algebraically largest and smallest principal stresses respectively, the value of the maximum shear stress is (Gate 2018 Mechanical Engineering)0 AnswerAt a critical point in a component, the state of stress is given as 100MPa xx , 220MPa yy , 80MPa xy yx and all other stress components are zero. The yield strength of the material is 468 MPa. The factor of safety on the basis of maximum shear stress theory is ______ (round off to one decimal place).0 Answer(Gate 2018 Mechanical engineering) The state of stress at a point, for a body in plane stress, is shown in the figure below. If the minimum principal stress is 10 kPa, then the normal stress y (in kPa) is 0 AnswerConsider the stress-strain curve for an ideal elastic-plastic strain hardening metal as shown in the figure. The metal was loaded in uniaxial tension starting from O. Upon loading, the stress-strain curve passes through initial yield point at P, and then strain hardens to point Q, where the loading was stopped. From point Q, the specimen was unloaded to point R, where the stress is zero. If the same specimen is reloaded in tension from point R, the value of stress at which the material yields again is _________ MPa.0 AnswerWhich one of following is NOT correct?
