According to the theory of strength, the bending moment of the hyperstatic beam at the central support is Mt = −27.5625 MNm . Solve the support reactions of the beam and draw the bending moment pattern when it is loaded with q = 14 MN/m . The dimensions of the beam are a = 3 m and b = 4.5 m .

In the questions, the point of view proceeds from left to right!

 

Shear force at x = 2.99 m just before the middle support reaction = ? MN

Bending moment at x = 3 m = ? MNm

The positive maximum of the bending moment between 0 < x < 3 m = MNm

The positive maximum of the bending moment between 3 < x < 7,5m = ? MNm
