Problem The beam is hinged supported at point ’a’ and supported by the bar at point ’c’. The cross section is presented in Fig.b. The load is a concentrated moment M at point ’b’ and the load intensity q between points ’c’ and ’d’. Both the bar and the beam are made of the same material of the Young modulus E. 1. Determine the reactions at point ’a’ and the force N in the bar. 2. Determine the minimum diameter D of the bar ’ce’ assuming the plastic limit Re and safety factor ns. 3. Find the translation of point ’d’. 4. Determine the location of the center of gravity of the cross section shown in Fig. 1b. 5. Calculate the moment of inertia according to the central axis yc. 6. Draw the plots of the shear forces T and bending moment M along the beam. 7. Calculate the maximum stress in the beam. When solving points 1-3 treat the beam ’ad’ as a rigid body.
