- I need help solving this problem. Please solve it and show your work.arrow_forwardAn overhanging beam is loaded as indicated. In order to accommodate communication cables to be installed later the beam is manufactured with two circular channels running through its length. The beam has a weight of q = 300 N/m. Calculate (a) the value and position of the maximum bending moment and sketch the relevant bending moment and shear force diagrams, (b) the position of the neutral axis, and (c) the maximum compressive and tension stress in the beam due to the bending. 2m 3 KN 3m B Bm 1 KN 100 mm 100 mm 20 mm H 30 mmarrow_forwardDraw the SFD and BMD for the beams loaded as shown in Calculate the position and magnitude of maximum bending moment and locate points of contra-flexures if any.arrow_forward
- please translate the following problem descriptions into al diagrammatic representation, solve for/draw the shear force and bending moment diagrams and find the deflection and/or slope as indicated: 3. A 16 ft. long simply supported beam is loaded by a 1 k/ft uniform distributed load for the first 6 ft. and (2) point loads, 3 kips each, at 9 ft. and 12 ft. A Structural No. 1 timber (E = 1,600,000 psi) is specified with nominal dimensions of 6x12. Find the magnitude and location of the maximum deflection.arrow_forwardCompute the initial deflection of the beam at midspan under service loads with the following specifications: f'c = 4000 psi, 36-inch height, depth of rebar assumed to be 3 inches less than the height, 16-inch width, 4 #9 bars (tension), Grade 60 rebar, 30' clear spans, service loads of: DL = 0.25k/ft, LL = 1.2k/ft. The DL does NOT include self-weight of the beam or of the precast concrete deck planks that have a weight of 60 PSF. The beam picks up a tributary width of 12 feet. Also, note that this beam is continuous and is the middle beam of 5 equal spans. Check the initial deflections against the ACI deflection requirements. Then calculate the long-term deflections and check those against the ACI requirements. For both situations, assume that finish materials will be attached to the beam. Last: Instead of performing a structural analysis to determine the maximum deflection in the beam, conservatively figure that the maximum deflection will be 60% of what it would have been for a…arrow_forwardA simply supported beam 10 m long has an overhang of 1.1 m at the left support. If a highway uniform load of 12.02 kN/m and a concentrated load of 194 kN, passes thru the beam, compute the maximum positive shear (kN) based on influence line for maximum shear at mid span.arrow_forward
