um bending stress acting at the cross-section a-a. The cross-section is solid circular with a dmd W n inertia about the NA, | = 4000 x 10 m?, 30 kN D =100 mm

The strut has a square cross section a by a and is subjected to the bending moment M applied at an angle as shown. Determine the maximum bending stress in terms of a, M, and u. What angle u will give the largest bendingstress in the strut? Specify the orientation of the neutral axis for this case.

The beam is supported by a pin at point A and a roller at kN point B. A distributed load of W₁ = 8 - and an applied m force of F₁ = 12 kN are applied to the beam. The beam has an allowable bending stress of allow = 6 MPa. Neglect the weight and thickness of the beam. Take the origin for all functions to be at A., i.e. start at the left and go right. Must use positive sign convention for V and M. d3 1 d3 d1 W1 d1 B O h d2 F₁ Values for the figure are given in the following table. Note the figure may not be to scale. Dimensions for the whole beam Variable Value d₁ 4 m d₂ 2 m

The shaft is subjected to the concentrated forces as shown in the figure below. There is a journal bearing at A and a thrust bearing at B. The allowable bending stress is σallow = 210 MPa. Determine, to the nearest mm, the smallest allowable diameter of the shaft.
