3. Determine the displacement of point B of the steel beam, and the slope at the left of point B. E= 200 GPa. I = 200x10^6 mm^4. 20 kN 10 kNm 3m 3m 4m hinge 21 I

A Douglas fir–larch 6 × 14 beam of No. 1 grade is 16 ft longand supports a total uniformly distributed load of 6000 lb. Investigate the deflection.

7) Are deflections for steel beam design determined with unfactored loads to compare to the code deflection limits?

Now consider the same beam when a 60-inch-long rod is added at mid-span. The rod's cross section area is 0.50 in². Find the axial stress in the rod, draw the shear and moment diagrams for the beam, and find the maximum stress in the beam. (Intermediate Result: Axial Force in Rod= 24,240 pounds.) 72 in B 200 lb/in ↓↓↓ 72 in с
