A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).
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.
answer this ; Let ? represent the reaction force at Support B. By releasing the beam at Support B and imposing a force ? at Point B, the deflection of the beam consists of two parts,i.e. Part I- the deflection caused by ?? ; Part II- the deflection caused by ? Please treat R, w, h , L , E as variables in this step , the mathematical equation for the deflection at Point B caused by ? ( Part II) can be written as (Hint : to input equation ?2??2?ℎ , you can type (R^2*L)/(Q^2*w*h) )
SHOW YOUR SOLUTIONS PLS, INSTRUCTIONS: For the beam shown, (1) derive equations for the shear force V and the bending moment M for any location in the beam. (Place the origin at point A.) (2) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Specify the values for key points on the diagrams. Let a=7.0 ft, b=8.7 ft, wa=13 kips/ft, and wb=7 kips/ft. QUESTIONS: 4) With reference to problem 1, what is the bending moment (in kip-ft rounded to the nearest whole number) at x = 9.0 ft? 5) With reference to problem 1, what is the maximum bending moment? Express your answer in kip-ft rounded to three significant figures.
Choose the correct option . In beam model, which of the following is proportional to curvature of deflection curve (a) Bending moment (b) first derivative of bending moment (c) third derivative of bending moment (d) second derivative of bending moment
In the elaboration of civil engineering works projects, the engineer needs to determine the forces that are required on beams, and the acting loads may act in different ways on them. The isostatic beams shown are subject to different load actuation. 1) In each case determine the reactions and diagrams of normal, shear and bending moments. Note: The correction will take into account the development and resolution of the question, therefore, a question only with the answer will be considered wrong.
Determine the internal bending moment as a function of x, and state the necessary boundary and/or continuity conditions used to determine the elastic curve for the beam. Please show brick-by-brick working thoroughly without taking the beeline so that I can understand clearly. Solve this problem thoroughly until the elastic curve(s) for the beam is/are obtained. Also, draw the dissected beam cross-section diagrams, including the equilibrium equations, when fathoming out the shear forces and internal bending moments. Topic: Solid Mechanics
The question answer includes 4 pages with 2 diagrams if u don't know the solution or is there a slight mistake i will downvote and will report to bartleby for revocation. Here is the question : A cantilever beam of length 1m carries a point load of 2000N at the free end. The cross-section of the cantilever is an unequal angle of dimensions 100mm by 60mm and 10 mm thick. The small leg of angle (i.e 60 mm) is horizontal. The load passes through the centroid of the cross-section. Determine: (i) Position of neutral axis; (ii) The magnitude of maximum stress set up at the fixed section of the cantilever.
I am trying to find the moment diagram of this beam but I keep getting graphs that don't make any sence how do I correctly do this problem?

Problem 1. Moment of Inertia Suppose we have elastic beams with cross-sections of the following shape: Assume the materials are all homogeneous and their elastic properties do not depend upon the cross section geometry. For each case: (1) Find the axes and Neutral Plane(s) for each cross-section, if the beam with such across-section would experience bending loads, and would deform and deflect. (2) For each Neutral Plane, calculate the Moment of Inertia.
