Kutukov B.N. 1990 Task 5 Option 015

For given two schemes of beams, it is required to write expressions Q and M for each section in general form, to plot the Q and M diagrams; find МMAX and select: a) for the scheme (a) a wooden beam of circular cross-section with [σ] = 8 MPa; b) for the scheme (b) a steel beam of I-section with [σ] = 160 MPa. Given: scheme 5; ℓ1 = 1.1 m; ℓ2 = 5 m; a1 / a = 10; a2 / a = 9; a3 / a = 5; M = 10 kNm; P = 10 kN; q = 5 kN / m.
