4. (20 pt) A wood beam AB on simple supports with span length equal to 9 ft is subjected to a uniform load of intensity 120 lb/ft acting along the entire length of the beam and a concentrated load P acting at a point 3 ft from the right-hand support (see figure). The allowable stresses in bending and shear, respectively, are 2500 psi and 150 psi. What is the allowable P? (Note: The width and height of the cross section...

An elevation of a concrete frame is shown below. A superimposed dead load of 200 lb/ft and a live load of 600 lb/ft are to be supported in addition to the beam self-weight. The beam's cross- section is shown as well. The weight density of reinforced concrete is 150 lbs/eu. ft. Use 1.2D+1.6L as your load combination. Use ACI moment coefficients and statics, as appropriate, to provide the Mu values for points A, B, C, and D. 48 5" 15"...

. Design a beam for a 30-ft simple span to support the working uniform loads of wo 1.25 k/ft (includes beam self-weight) and wi-1.75 k/ft. The maximum permissible total load deflection under working loads is 1/360 of the span. Use 50 ksi steel and consider moment, shear and deflection. The beam is to be braced laterally at its ends and the mid-span only. (25-POINTS)
