The number of cycles depends on the stress amplitude a. The relationship between aand N expresses the so-called S-N curve of the material. At high stress,the material breaks rapidly - Fatigue limit between 1 and 1000 cycles At a lower stress in the material,it can withstand more than 10,000 to 10,000,000 cycles[Solved] The figure shows a horizontal steel bar of Find the load F that will cause an allowable shear stress, solvedthe allowable shear stress for the material is tul#207;allow,in the throats of thewelds.Students also viewed these Mechanical Engineering questions The figure shows a horizontal steel bar 3/8 in thick loaded in steady tension and welded to a vertical support.What is Stress-strain Curve - Stress-strain Diagram This theory states that failure of a piping component occurs when the maximum shear stress exceeds the shear stress at the yield point in a tensile test.Ductile vs.Brittle Stress-strain curves Some materials break very sharply,without plastic deformation,in what is called a brittle failure.
