What is the Shear Force,V?

Learning Goal: To calculate the shear stress at a point in the web of an l- beam section subjected to a shear force. When a beam section is subjected to a shear load, a shear stress distribution is developed on the section. The distribution of the shear stress is not linear. Elasticity theory can be used to calculate the shear stress at any point. However, a simpler method can be used to calculate the average shear stress across the width of the section, a distance y above or below the neutral axis. The average VQ shear stress is given by T = Here V is the shear It force on the section, I is the moment of inertia of the entire section about the neutral axis, and ₺ is the width of the section at the distance y where the shear stress is being calculated. Q is the product of the area of the section above (or below) y and the distance from the neutral axis to the centroid of that area (Figure 1). In short, Qis the moment of the area about the neutral axis. Figure 1 of 1 An I-beam has a…

What is the shear force (in kips rounded to the nearest whole number) at x = 6.0 ft?-  What is the bending moment (in kip-ft rounded to the nearest whole number) at x = 6.0 ft? What is the shear force (in kips rounded to the nearest whole number) at x = 9.0 ft? What is the bending moment (in kip-ft rounded to the nearest whole number) at x = 9.0 ft?  What is the maximum bending moment? Express your answer in kip-ft rounded to three significant figures.

Is the axial stress generally smaller than the stress developed by shear?

please do fast i will give you thumbs up
