Kutukov B.N. 1990 Task 5 Option 035

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 5; ℓ1 = 1.3m; ℓ2 = 5m; a1 / a = 10; a2 / a = 7; a3 / a = 5; M = 10 kNm; P = 3kN; q = 5kN / m.
