Problem:
The structure in Figure 01 is made up of a steel (E = 200GPa) rectangular beam ABC with depth h= 40 mm and width b = 30 mm and two wood (E=10 GPA) pin-connected members BD and CD with 25 mm square cross section. If load P= 9 KN is applied to the beam at C, determine the reaction at support D and maximum stress in the steel beam and wood members.
Figure 01: Problem Structure.
(Note: A is fixed and D is roller support) R D = 13.086 KN
Analytical answer: Maximum stress in the steel beam 92.1 MPa and maximum stress in wood
13.1 Mpa. (10% error is acceptable in numerical solution)
