Question

Item 3 Part B What are the expressions for the shear, V, and the bending moment, M, within the beam between points A and B in terms of Ay and z, the arbitrary distance to the sectional cut from the beam's left end? Express your answers in terms of some or all the variables Ay and z separated by a comma. Hints Learning Goal To create shear and bending-moment diagrams from shear and moment functions When designing beams, engineers require detailed information about the variation of the internal shear force, V, and the bending moment, M, that act at each point along the beam's axis. The variations of V and M as functions of the position z along the beam's axis can be obtained by using the method of sections, where an arbitrary location is chosen to section the beam rather than a specific point. Submit My Answers Give Up Correct It is important to use the correct sign conventions shown below for V and M in the free-body diagrams Part C What are the expressions for the shear, V, and the bending moment, M, within the beam between points B and C in terms of Ay, Mi, and z, the distance to the sectional cut from the beam's left end? Express your answers in terms of some or all the variables Ay, Mi, and z separated by a comma. Hints Positive shear ? V. M = Positive moment If the sign conventions are followed, then the resulting values for V and M will have the correct sign, and it is crucial to know during the design of a structure whether V or M in a particular section of a beam is positive or negative Submit My Answers Give Up Part D What are the expressions for the shear, V, and the bending moment, M, within the beam between points C and D in terms of Ay, Mi, I, w, and z, the distance to the sectional cut from the beam's left end? Express your answers in terms of some or all the variables Ay, 4J, w, and z separated by a comma. Hints ! ? V. M = Submit My Answers Give Up Part E

Explanation / Answer

c.) V = Ay
M = M1 + Ay*x

d.) V = Ay - wx
M = M1 + Ay*x - wx2/2

These should be the most probable answers. I don't have the image in the question. please verify the answers with diagrams. procedure will be same.
