4 - A rectangular block is loaded with a 180 kN axial force and a moment M, as shown in the figure. If the maximum allowable tensile stress is 50 MPa, what is the allowable magnitude of the moment? 60mm 100mm 국 Cross-section 180KN M elevation view -X

4. The general stress element is loaded such that ơx = 30 MPa, oy = -20 MPa, Txy = 5 MPa. Using Mohr's circle, find out the maximum normal stress and shear stress acting on this element. 5. The general stress element is loaded such that ơ, = 50 MPa. Using Mohr's circle, find out the maximum normal stress and shear stress acting on this element. (Simple tension)
