Kutukov B.N. 1990 Task 5 Option 888

For the given two beam schemes, it is required to write the expressions Q and M for each section in a general form, and plot the Q and M plots; find MMAX and select: a) for the scheme (a) a wooden beam of circular cross section at [σ] = 8 MPa; b) for scheme (b) a steel beam of I-section at [σ] = 160 MPa. Given: Scheme 8; ℓ1 = 1.8 m; ℓ2 = 8m; a1 / a = 8; a2 / a = 8; a3 / a = 3; M = 8kNm; P = 8kN; q = 8N / m.
