Design engineers in many situations must justify their selection of beams and pin-ended columns used in various nachines. Your role in a mechanical design company that manufactures gearboxes and gearbox mounting platforms is to analyse the rolled steel beams and columns under study (see Fig.4). Your manager asked you o properly select one rolled steel beam and one rolled steel column for the design and to provide your ustification of this selection, if the following design requirements are given: Beams and columns are made of ASTM-A709/Grade 345 - Factor of Safety (F.S) is 1.2 - Buckling Euler conditions must be met. Beams are subjected to 50 kN axial force. Beam (A) has radius of 13 mm. Beam (B) has radius of 5 mm. Column (A) is subjected to 15 kN axial force. Column (A) has length of 1.5 m and radius of 10 mm.

Floor joists are structural members which support flooring in structures, as in the diagram on the right. The floor sits upon the minor length of the joist, and the joists are set at equal spacing to reach the desired floor stiffness. How many 2x6 joists would it take to equal the floor stiffness of the same floor supported by ten (10) 2x12 joists of the same species?
When a beam 6 m long with a cross-sectional area of 19.4 cm2 is subjected to a compression force of 16 x 104 N, its length is shortened by 4.5 mm. What is the Young’s Modulus for the beam?
In order to determine the magnitude of the internal forces, a FBD must be cut. It is difficult to determine where a cut should be made in order to reveal the Maximum Internal Forces, thus we have put the distance to the cut in terms of 'x', and plot the equation. In my lecture we took a generic portion of a Beam and applied equilibrium and saw that Loading, Shear and Moment are related to each through differential equations. Change in Shear is the Area under the Loading diagram. Change in Moment is the Area under the Shear Diagram. Using Graphic Integration draw the shear and moment diagrams for the given beams and loading.
Materials such as ordinary concrete and stone are veryweak under tension or shear. Would it be wise to use sucha material for either of the supports of the cantilevershown in Fig.? If so, which one(s)? Explain.
Consider a 2-meter simply supported beam with a circular cross section. The beam is subjected to a point load of 1000N at its center. What is the minimum diameter (in meters) of the beam necessary for the normal stress to remain below 10MPa? Given the diameter found in the previous problem and under the same loading conditions, what is the maximum shear stress? Give your answers in MPa.

Hey, please reply as soon as posible Static Problem Make the shear force and bending moment diagrams on ABCDE. Also find the maximum values of shear force and bending moment (indicate the magnitudes of the maximum values and their location in the beam). You must justify the shape and values of the graphics you present. Consider that, in addition to the beam, there is a box with a "Weight" that is supported by the beam itself and the wall, by means of an arrangement of cables attached to the F ring. Consider the information provided on the reactions at points A and D. In the case of point A the only vertical reaction is supplied, directed downwards. important data: a = 285 m, b = 190 m, d= 380 m, e = 1995 m, f = 95 m, g = 190 m. Load in N/m, w=2,105 N/m.
