Now, if the end of the bar marked by the red circle in the figure below is the only spot where you can apply loadson the bar. Draw loads accompanied with magnitudes only at the indicated end in the figure below, so that the ground experiences the same loading from the bar

A cross-section of a beam is shown in Figure Q2. If the shear force in this section is V determine the value and the location of the maximum shear stress in the section. In Figure Q2, a = 68 mm and the origin of the coordinate system is at centroid of the cross section. y= A Z= a I₂ = S = AY mm; Figure Q2 Answer The vertical coordinate (y-coordinate; the y-axis serves as the axis of symmetry of the cross- section.) and horizontal coordinate (z-coordinate) of the location where the maximum shear stress occurs in the section are mm; O 4a Tmax= The vertical distance from the location where the maximum shear stress occurs in the section to the bottom side (AB) of the cross section can be calculated as Distance = mm B Second moment of area The second moment of area employed in the equation to calculate maximum shear stress can be calculated as Shear stress a (units : mm¹ ) First moment of area The first moment of area employed in the equation to calculate maximum shear stress can be…

Question 13 Use the diagram shown above. Given • D₁ = 9 ft D₂=7 ft D₂ 3 D3-4 ft • W = 100 #/ft P = 800 # D. 1 D₂ X W P Solve for the internal moment at X. Note: Enter the numerical value only for your calculation results. You'll be asked to specify the unit for your calculation result in the following question. (This is due to Canvas' lack of ability to require units for calculation question.)

i) the position of maximum displacement in the segment AB. Hint: remember that coordinate x1 is measured from support A, thus the position of max. displacement will be measured from point A. Enter your answer in m to 3 decimal places.
