Consider the bar/roller assembly shown in the figure below. The roller and surface at point A are frictionless. Two loads are applied to the bar: a couple-moment and a force, as indicated in the figure. 1. Draw a FBD which is suitable for solution of this problem, when seeking to find the reactions at the supports, Points A and B. You must draw a separate diagram and you may NOT use the existing figure given here. In your FBD, it is essential that you make clear precisely what object or collection of objects actually defines your “free body". Your FBD must clearly/correctly show all reactions at the supports, Points A and B, in addition to the applied load(s). You may neglect the weight of the assembly in this problem. The FBD should define the positive “x" and “y" directions, and include the dimensions necessary for computing moments. 2. Write the equilibrium equations and solve for the reactions at the supports (the roller, Point A and the pin, Point B). You must be clear in your results with respect to the direction in which the reactions act on the body. Express results in units consistent with that of the given figure.

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Question

Consider the bar/roller assembly shown in the figure below. The roller and surface at point A are
frictionless. Two loads are applied to the bar: a couple-moment and a force, as indicated in the
figure.
1. Draw a FBD which is suitable for solution of this problem, when seeking to find the
reactions at the supports, Points A and B. You must draw a separate diagram and you
may NOT use the existing figure given here. In your FBD, it is essential that you make
clear precisely what object or collection of objects actually defines your “free body".
Your FBD must clearly/correctly show all reactions at the supports, Points A and B, in
addition to the applied load(s). You may neglect the weight of the assembly in this
problem. The FBD should define the positive “x" and "y" directions, and include the
dimensions necessary for computing moments.
2. Write the equilibrium equations and solve for the reactions at the supports (the roller,
Point A and the pin, Point B). You must be clear in your results with respect to the
direction in which the reactions act on the body. Express results in units consistent with
that of the given figure.

A pin in a knuckle joint carrying a tensile load Fdeflects somewhat on account of this loading, making the distribution of reaction and load as shown in part (b) of the figure. A common simplification is to assume uniform load distributions, as shown in part (c). To further simplify, designers may consider replacing the distributed loads with point loads, such as in the two models shown in parts (d) and (e).
