In the classic Ritter-Mörsh truss, the inclination angle of the compressed struts is equal to 45°. The force acting on the compressed strut (R) can be deduced by similarity of triangles and results in . A 20 x 40 cm beam with an effective span of 6.0 m and concentrated loading at the central part of 30 kN, cover of 3 cm, resulting in an internal truss. Based on this information, choose the alternative that indicates what is the resultant force in the compressed strut:


a. 19.96 kN.m
b. 30.50 kN.m
c. 37.06 kN.m
d. 40.82 kN.m
e. 21.21 kN.m
