Question 4 At a point in a material there are two direct stresses of 60 MPa tensile and 50 MPa compressive acting at right angles to each other. The greatest principal stress in the material is limited to 125 MPa in tension. What will be maximum shearing stress to which the material can be subjected on the given plane

At a point in a strained material, tensile stress of 100 MPa and compressive stress of 60 MPa are found to be principal stresses Maximum shear stress at that point is: O 60 MPa O 20 MPa O 40 MPa O 80 MPa

At a particular point in a structural member a direct tensile stress of 60 N/mm² exists on a plane perpendicular to the longitudinal axis of the member while a direct compressive stress of 40 N/mm? occurs on a plane parallel to this axis; in addition shear and complementary shear stresses of 50 N/mm? act on these planes. If Young's modulus E is 200000 N/mm² and Poisson's ratio v is 0.3 calculate the direct and shear strains on these planes and hence, using a graphical method, determine the principal strains at the point, the maximum shear strain and the angle the plane of maximum principal strain makes with the longitudinal axis of the member. Finally, calculate the principal stresses at the point. Ans. E= 3.6x104, ɛ, = -2.9x104, Yy=6.5x10-4 ɛ1 = 4.95x10, 01 = 80.8 N/mm², o1=-60.8 N/mm. Ɛ11 =-4.25x10 Ymax=9.2x10-, 67.5°

At a point in an elastic material under strain, there are normal stresses of 60 N/mm2 and 40 N/mm2 (both tensile) at right angles to each other, with positive shearing stress of 20 N/mm2. The maximum shear stress and direction its plane will be respectively

A homogenous isotropic material of size 20 cm x cm x 20 cm is placed inside a rigid box of internal dimension 20 x 20 x 20 cm. The top of the box is open and the material inside is subjected to a uniform compressive stress of 10 N/mm² from the top. Assuming there is no friction between the surface of contact, find the stresses on the side faces of the material. Also find maximum shear stress, the normal stresses on the plane of maximum shear stress and the change of volume of the material. Young's modulus E is 1 x 105 N/mm² and Poisson's ratio, m = 0.3 for the material. S 10 N/mm² 20 cm 20 cm-
