a 50mm x 200mm beam is supported has a 2kN load placed 1m from the left reaction. calculate the maximum bending stress when the beam is lying on edge and when lying flat (lying on edge = 33 x 10^-6 m^4 lying flat = 2.08 x 10^-6 m^4)

A beam has a bending moment of 3.5 kN-m applied to a section with a hollow circular cross-section of external diameter 3 cm and internal diameter 2.3 cm . The modulus of elasticity for the material is 210 x 109 N/m2. Calculate the radius of curvature and maximum bending stress. Also, calculate the stress at the point at 0.6 cm from the neutral axis (i) The moment of inertia in (mm^4)=  ii) The radius of curvature in (mm) = (iii) The maximum bending stress  in (N/mm^2)= iv) The bending stress at the point 0.6 cm from the neutral axis  in (N/mm^2)=

Draw the free body diagram, shear force diagram, and bending moment diagram for the beam shown below and calculate values at each point:
