In a bending test for a brittle material, the distance between the supports is 300mm, the cross sectional area of the specimen is 1200 mm? and the thickness is 30mm. find the transverse rupture strength if the applied load was 1 ton.

6. Derive the resolved shear stress(RSS) equation for dislocation at an arbitrary plane at angle (e) with horizontal under nominal axial tensile stress(o) and plot the variation of Schmidt factor with

A critical point in a part made of a ductile material is subject to the following state of plane stress: 15ksi, 30 ksi, 15 ksi, Ox,min = -35 ksi, Oy,min = 30 ksi, Txy,min = -15 ksi. Ох,max бу,max Тxy,max %3D There are no stress concentrations. The load line is propositional. The material has a yield strength of Sy = 130 ksi, an ultimate strength of Su = 200 ksi, and a fully corrected endurance limit of Sn : 75 ksi. Calculate the: (a) Static factor of safety using the MSSTF, (b) Static factor of safety using the DETF, (c) Fatigue factor of safety using the Soderberg criterion, (d) Fatigue factor of safety using the Goodman criterion, (e) Fatigue factor of safety using the ASME elliptic criterion.

A hot rolled steel tension test sample has a diameter of 6 mm and the original gage length of 30 mm. In a test to fracture, the stress and strain data below were obtained. Determine Generic Strain Value, %0.2 offset strain, and Calculated stress at %0.2 offset. Original diameter - 6mm Original Length - 30 mm Fracture diameter - 4.54 mm
