The maximum bending stress at distance 0.5 m from the built-in right hand end in the structural beam of uniform rectangular cross-section shown in the figure, is, kN 1m 10 mm O a. 750 kNmm2 O b.75 MNM2 OC 750 MNm-2 O d. 1500 Nmm2

Determine the axial force, shear force, and bending moment at point J located on member AB of the landing gear of an airplane, as shown in the figure.All distances are in inches.

The bending moment in a horizontally placed beam at distance x from one of the ends is given by the expression M = 13x - 3x - 12 . The shear force in the beam is zero at, O a. x = 7.12 O b.x = 3 and x = 1.33 O C. X = 2.16 O d. Need more data and a figure to solve the problem.

The cross-sectional dimensions of a beam are shown in the figure. Assume a = 45 mm, b = 75 mm, t = 4 mm and d =55 mm. (a) If the bending stress at point Kis 54 MPa (C), determine the internal bending moment M₂ acting about the z centroidal axis of the beam. (b) Determine the bending stress at point H. The bending stress is positive if in tension and negative if in compression. IT H Answers: (a) M₂= (b) og = i 945.9 144.881 d N-m MPa
