Calculate the maximum shear stress in the beam cross-section. [38 N/mm2 ] 13 State the conditions which identify a complex-stress situation. 14 If a component is subjected to an external shear stress, work from first principles and show that there will also be a complementary shear stress acting. In such a component, the applied shear stress is 30 N/mm2. Calculate the normal and shear stresses on a plane which is inclined at 30° to the plane on which the applied shear stress is acting. [26 N/mm2 ; 15 N/mm2 ] 15 Working from first principles, derive an expression for the magnitude of the normal and shear stresses on any plane in an element subjected to normal stresses only.

Scaling the Mohr's stress circle, fig. e. compressive) and circle radius = T max . 1 N/mm 2 . 3 (ACW) σ =0 All stresses in N/mm2 Scale: 1 mm = 1 N/mm 2 (b) Fig. 7 (a) All stresses in N/mm 2 Scale: 1 mm = 1 N/mm 2 (b) Fig. 27(a) shows a point in the shaft where the bending stress is a maximum compressive value. As before, ox = 0. Scaling the Mohr's stress circle, fig. e. compressive) and circle radius = r m a x . 1 N/mm 2 . Note that the major principal stress ox is the tensile value even though its numerical value is smaller than σ 2 , which is compressive.

4N/mm2 ] 32 At a point in a material, a tensile stress of 60N/mm2 acts together with a clockwise shear stress of 15 N/mm2, while on a mutually perpendicular plane there is a compressive stress of 20 N/mm2 and an anticlockwise shear 42 stress of 15 N/mm2. Working from first principles, find the normal and shear stresses on a plane inclined at 40° (measured clockwise) to the plane of the tensile stress. Construct a Mohr's stress circle to verify your answers. 8 N/mm2 ] 33 The principal stresses at a point in an element are 80 N/mm2 (tensile) and 30N/mm2 (compressive).
