Objectives

Review solving for shear, moment, and axial diagrams for determinate, stable frames

Practice presenting frame solutions in the format expected for this class

Practice Problems

If you feel you need extra review on solving frames or creating shear, moment, and axial diagrams for them, feel free to practice with any problems in your textbook Chapter $5.$ If you have questions or would like to check your solutions, feel free to stop by office hours.

Assignment

Problem $1$

For each of the frames in Figure $1,$ solve for the reactions and draw the axdal, shear, and moment diagrams. Your final answers and presentation of them is the only thing that will be graded, so you need only show the work you needed to arrive at the answer. For each frame, your final presentation must include the following:

A free body diagram $($F$.$B$.$D$.)$ for the full frame showing all applied loads and reactions. Arrows showing reactions must indicate the direction the reaction acts.

Separate F$.$B$.$D$.\text{'}$s for each member that shows all applied loads and the member end forces

Separate axial, shear, and moment diagrams must be provided for each member $($that is$,$ an exploded view as shown in class$),$ with the diagrams oriented in the direction of the member

Axial load diagram must label the forces as tension $($T$)$ or compression $($C$)$

Shear diagrams must label the following values:

Shear at ends of the frame members

Shear on both sides of a jump in the shear diagram

Maxima$/$minima shears

Location of zero shear force $($you need this to determine the maxima$/$minima moments!$)$

Moment diagrams must be drawn on the compression side of the frame member, with labels for the following values:

Moment at ends of the beam

Moment on both sides of a jump in the moment diagram

Maxima$/$minima moments
