326 СНАРТER 6 BENDING EXAMPLE 6.18 The reinforced concrete beam has the cross-sectional area shown in Fig. 6-39a. If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...

The queen-post trussed beam is used to support a uniform load of 4 k/ft. Determine the force developed in each of the five struts. Neglect the thickness of the beam and assume the truss members are pin connected to the beam. Also, neglect the effect of axial compression and shear in the beam. The cross-sectional area of each strut is 3 in2, and the moment of inertia for the beam is 600 in4. Also, E 29(103) ksi. Prob. 9-36 4...

Do not round intermediate calculations. Give your final answer(s) to three significant figures. Rod B D is made of steel (E -29 x 10* psi) and is used to brace the axially compressed member ABC. The maximum force that can be developed in member BD is 0.02P. If the stress must not exceed 18 ksi and the maximum change in length of BD must not exceed 0.001 times the length of AB C, determine the smallest-diameter rod that can be...
