A simply supported wood beam with a span of L = 14 ft supports a uniformly distributed load w. The beam width is b = 7 in. and the beam height is h = 14 in. The allowable bending stress of the wood is 810 psi. Determine the magnitude of the maximum load w that may be carried by the beam. Answer: w = Mi lb/ft.

A timber beam of rectangular section carries a load of 2 kN at mid-span. The beam is simply supported over a span of 3.6 m. If the depth of section is to be twice the breadth, and the bending stress is not to exceed 9 N/mm2 , determine the cross-sectional dimensions.

M = 2. A beam of length 10 m and of uniform rectangular section is supported at its ends and carries uniformly distributed load over the entire length. Calculate the depth of the section if the maximum permissible bending stress is 16 N/mm² and central deflection is not to exceed 10 mm. Take the value of E = 1.2 × 104 N/mm². Use the following g equations: w.L² 8 ус W.L 161 8 d = 2 W.L 8 == WL³ 5 384 ΕΙ (: W = w.L)

Determine the maximum bending moment for the beam shown below. Use a = 8 ft, b = 12 ft, c = 6 ft, and w = 12 kips/ft. The reaction forces for this beam are Ay = 66.5 kips and Dy = 77.5 kips. B a b Answer: Mmax = i kip-ft

The horizontal beam ABC of an oil-wellpump has the cross section shown in the figure. If thevertical pumping force acting at end C is 9 kips andif the distance from the line of action of that force topoint B is 16 ft, what is the maximum bending stressin the beam due to the pumping force?

None

If Mz = 715 kip-ft, find the magnitude of the bending stress at a point H.    For the beam cross section, assume a = 10 in. b = 14 in. d = 39 in. r = 5 in.   The centroid of the cross section is located 17.9 in. below the uppermost surface of the beam.  The moment of inertia about the z axis is 60436 in.4.

The cross section of a wood beam carries a bending moment M of magnitude 20R lb.-in. acting at 100 to the horizontal. Determine(a)the angle between the neutral axis and the horizontal; and (b) the maximum bending stress acting on the cross section. Note R=993

A simply supported wood beam with a span of L-9 ft supports a uniformly distributed load w. The beam width is b-5 in, and the beam height is h=9 in. The allowable bending stress of the wood is 980 psi. Determine the magnitude of the maximum load w that may be carried by the beam. Answer: W- i| 1 lb/ft.

The simple beam AB, shown below, supports a concentrated load of 6 kN and a segmentof non-uniform load of intensity varies from 1 kN/m to 3 kN/m at point B. a). Determine the maximum bending stress and the maximum shear stress acting on the beam if the beam has a rectangular cross section of (500 mm × 200 mm).
