Kutukov B.N. 1990 Task 5 Option 026

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 6; ℓ₁ = 1.2 m; ℓ₂ = 6 m; a₁ / a = 10; a₂/ a = 8; a₃/ a = 1; M = 10 kNm; P = 20 kN; q = 6 kN / m.
