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 = 1.5 m; ℓ2 = 5m; a1 / a = 5; a2 / a = 5; a3 / a = 5; M = 5kNm; P = 5kN; q = 5N / m.
