Displacement of a steel rod - don't know how to begin

AI Thread Summary
To determine the displacement of point C on the A-36 steel rod, start by analyzing each force acting on the rod separately. Calculate the displacement caused by each force using the modulus of elasticity for steel and the appropriate displacement formula. It's important to note that under the 9 N force, point C does not experience any displacement. Finally, sum the individual displacements to find the total displacement at point C. Understanding these principles will help in solving the problem effectively.

The A-36 steel rod is subjected to the loading shown.

If the cross-sectional area of the rod is 50 mm^2, determine the displacement of C.
Neglect the size of the couplings at B, C, and D.

Please help, I don't have any idea how to begin. I can't seem to sum the forces right.

It is best to look at each force separately, find the displacement at C under each force, and then add up the results. You have to know the modulus of elasticity of the steel, and the displacemnt formula. Note that under the 9 N force, point C just goes along for the 'ride'.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
