Question: 2 a thin rectangular plate of dimensions 75mm by 200mm...

Question details

2) A thin rectangular plate of dimensions 75-mm by 200-mm is formed by welding together two triangular plates. The plate is subjected to a 3MPa compressive stress across the short edge and a 10 MPa tension stress across the long direction. 10 MPa 一心 75 mm 3 MPa a.) Determine the normal stress acting perpendicular to the weld and the shear stress acting parallel to the weld. 200 mm b.) If the weld material has a maximum allowable normal stress of 8MPa, is this design safe? What is the margin of safety (MS)?
