Topics Since Exam 2 Shear and Moment Diagrams Torsion Bending Transverse Shear

Shear and Moment Diagrams If provided a FBD, can you create a correct shear diagram? If provided a FBD, can you create a correct moment diagram? If provided a shear diagram, can you create a moment diagram If provided a moment diagram, can you create a shear diagram?

Torsion If you are given a picture of a shaft with multiple torque inputs, can you determine the torque in any given segment of that shaft? Can you solve for the angle of twist of any segment of a shaft? Do you know how to calculate J for solid and hollow shafts? What does the variable c represent in the equation below? Where is the location of highest shear?

Bending Can you solve for the bending stress at any location in a beam by knowing the radius of curvature and the beam cross section? Can you solve for the bending stress at any location in a beam by knowing the moment and beam cross section? Can you calculate Iz for a beam cross section?

Horizontal Shear Can you solve for the horizontal shear stress at any location in a beam? Can you solve for Q at any point in a beam? What is the variable t in the equation for shear stress below?
