What should be the yield strength of A36?
The American Society for Testing and Materials (ASTM) designate A36 by both its chemical composition and mechanical properties, especially yield strength which must reach a minimum of 250 MPa or 36000 psi.See all results for this questionWhat kind of work can A36 steel be used for?It is ideal for grinding, tapping, drilling, punching and machining. A36 is often galvanised to prevent corrosion. Other industries that frequently use A36 steel include automotive, aerospace, oil and gas and manufacturers of heavy machinery.See all results for this questionWhat is the axis of a burr grinder?The burr grinding procedure is illustrated in Fig. 3.3. The burr is centered over the weld toe. The axis of the tool should be 45-60° to the main plate, and approximately 45° to the direction of travel. The grinder can be either pushed or pulled along the weld. Usually the former is more successful at establishing a straight groove of even depth.See all results for this question

Stress Symptoms: Physical Effects of Stress on the Body
The first step to controlling stress is to know the symptoms of stress. But recognizing stress symptoms may be harder than you think. Most of us are so used to being stressed, we often don't know we are stressed until we are at the breaking point.See more on webmd a36b fatigue dabta GrindingRolling Bearing Steels - A Technical and Historical a36b fatigue dabta Grindingfatigue data from six different labora-tories in Japan for AISI 52100 steel. He also presented stress/life fatigue data for axial loading. The resultant lives were in excess of one billion (>109) stress cycles at a maximum shearing stress max as low as 350 MPa (51 ksi) without an apparent fatigue limit. In 2008, Tosha et al.
