- (use EI constant for whole span). A 10-meter-span, propped beam (fixed at the left support and roller at right support), with a uniformly distributed load from left support to six meters to the right, with a magnitude of six kilonewton per lineal meter, a downward concentrated load at the midspan. Solve the reactions at the fixed support and roller support, slope and deflection at the roller support, using Area Moment Method. Use the concentrated load as 24 kN.For the truss given below, it is desired to determine the normal efforts that act on the members, so that, thus, possible constraints for its design are possible. Consider that at point A there is a second gender support; and at point D, a first-class support. As this is asked: what is the effort acting on bar AB? Is it guidance or assessment?Source: Hibbeler (2004, p. 588). HIBBELER, R. C. Resistance of Materials. 5. ed. Rio de Janeiro: Technical and Scientific Books Publisher, 2004. Question 1 options: a) A compression force of 100 kN acts on bar AB. B) A tensile effort of 100 kN acts on bar AB. c) A compressive force of 141.42 kN acts on bar AB. d) A compression force of 200 kN acts on bar AB. e) A tensile effort of 141.42 kN acts on bar AB.Beam ABC is subjected to the loading shown, where Pb = 55.0 kN . The measurement corresponding to the half-length of the beam is a = 2.00 mm . For the cross section shown, b = 70.0 mm , c = 150.0 mm , ddd = 125.0 mmmm , and e = 50.0 mm . Point D is located at the centroid of the cross section and point E is located directly above the transition between the web and the top flange. Part A draw free body diagram? Part B - Maximum shear force Determine the maximum shear force, Vmax, in beam ABC. Vmax =? Part C - Shear stress at point D Determine the shear stress, τD, at point D that corresponds to the maximum shear force along the length of the beam. τD =? Part D - Shear stress at point E Determine the shear stress, τE, at point E that corresponds to the maximum shear force along the length of the beam. τE =?
- A Simply supported beam of effective span 6 m carries three point loads of 30 KN, 25 KN and 40 KN at 1m, 3m and 4.5m respectively from the left support. Draw the SFD and BMD. Indicating values at salient points.Compute 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…What is the force reaction at the fixed end of a 12-m cantilever beam due to a downward uniform load of 30 kN/m applied throughout the span? (Answer must be in kN.)

Question 1-C) to the point in x direction ( A x ) Determine the support reactions. ( Enter yourresult without writing kN units.)Can you provide me the step by step solution of this? Thank you! Determine the magnitude of the vertical force Ay for the simply supported beam, where w = 9 kips/ft, L1 = 12 ft, and L2 = 4 ft.
- Draw the free-body diagram for the following problem.The beam shown.A pontoon bridge (see figure) is constructedof two longitudinal wood beams, known as balks,that span between adjacent pontoons and supportthe transverse floor beams, which are called chesses.For purposes of design, assume that a uniform floorload of 7.5 kPa acts over the chesses. (This loadincludes an allowance for the weights of the chessesand balks.) Also, assume that the chesses are 2.5 m long and that the balks are simply supported with aspan of 3.0 m. The allowable bending stress in thewood is 15 MPa.(a) If the balks have a square cross section, what istheir minimum required width bmin?(b) Repeat part (a) if the balk width is 1.5 b andthe balk depth is b; compare the cross-sectionalareas of the two designs.A 2500 lbs point load is placed at 4 inches from support A. The beam is simply supported with a span of 16 inches. Determine the maximum flexural stress of the beam.
