A beam supports both a uniform distributed load and a concentrated force, as shown in the figure below. The 0 ft to L₂ = 6 ft to the right uniform distributed load has a magnitude q = 80 lb/ft and extends from L₁ of point A. The concentrated force has a magnitude F = 300 lb, is inclined by an angle 0 = 40°, and acts L3= 10 ft to the left of point B. The beam has an overall length L = 20 ft, and is held in equilibrium by a pin at point A and a roller at point B. Neglect the height and weight of the beam for this analysis. Determine the support reactions at points A and B. Note: Express your answers following the standard sign convention for the coordinate system shown.

Two street lights are mounted as shown in the figure one at A and the other at C. The member AD is able to freely rotate about D. Member BE is a steel cable. B. EACH street light has a mass of 5 kg, AB=20cm, BC=20cm, CD=10cm, DE=17.32cm. Assume gravity is 9.81 N/kg. h=4cm Draw the shear force profile (a) between point A and D. On the diagram, clear indicate the values on the diagram. (b) member just to the right of point B. Calculate the maximum bending shear stress. At what distance from the bottom does it occur? Consider a cross-section of the (c) distance from the bottom does the minimum bending shear stress occur? What is its value? For the same cross-section, at what

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.

In the following figure, there are two equal couples with a magnitude of M = 15 kNm. They act in opposite directions while being applied to the channel beam AB. These couples cause the beam to bend in the horizontal plane. Find: 1) Stress at point C 2) Stress at point D 3) Stress at point E
