The state of stress at a point in a loaded member is shown in figure. The magnitude of maximum shear stress is
At a point in a strained body carrying two unequal unlike principal stresses p_{1} and p_{2} (p_{1} > p_{2}), the maximum shear stress is given by
The radius of Mohr’s circle of stress of a strained element is 20 N/mm^{2} and minor principal tensile stress is 10 N/mm^{2}; The major principal stress is
The principal stresses σ_{1} , σ_{2} and σ_{3} at a point respectively are 80 MPa, 30 MPa and 40 MPa. The maximum shear stress is
Plane stress at a point in a body is defined by principal stress 3σ and σ. The ratio of the normal stress to the maximum shear stress on the plane of maximum shear stress is
A shaft subjected to torsion experiences a pure shear stress τ on the surface. The maximum principal stress on the surface which is at 45° to the axis will have a value
Principal strains at a point are 100 x 10^{6} and 200 x 10^{6}. What is the maximum shear strain at the point?
In a plane stress problem there are normal tensile stresses σ_{x} and σ_{y} accompanied by shear stress τ_{xy} at a point along orthogonal Cartesian coordinates x and y respectively. If it is observed that the minimum principal stress on a certain plane is zero the
A point in a strained body is subjected to a tensile stress of 100 MPa on one plane and a tensile stress of 50 MPa on a plane at right angle to it. If these planes are carrying shear stresses of 50 MPa, then the principal stresses are inclined to the larger normal stress at an angle of
If the normal crosssection A of a member is subjected to a tensile force P, the resulting normal stress on an oblique plane inclined at angle θ to transverse plane will be
