A wire cutter is shown in the figure above. A value can be chosen for the length A-B. The handles are loaded with a force of 225 N. The cross-section a-a is shown in the figure, in which point E is indicated. The pliers are made from 100 MnCrW4, a low alloy, cold working, oil hardening malleable tool steel. This material has an E-modulus E = 200000 MPa, a yield strength oy = 550 MPa and a Poissons ratio of v=0.27. The material is linear elastic and isotropic after tempering. a) Determine the normal and/or shear stress(s) at point E in section a-a. b) Sketch the element of the plane state of stress at point E.
