Solution: The rigid bar is pinned at A and supported by two

Problem 4-52

The rigid bar is pinned at A and supported by two aluminum rods, each having a diameter of 1 in. and a modulus of elasticity  ksi. If the bar is initially vertical, determine the force in each rod when the 2-kip load is applied.

                                                              Step by Step Solution

Step 1 of 3

Take the equilibrium equation around the x axis we get:(refer to figure 1)

....(1)

                                 Figure 1

Next talking the momentum equilibrium around A with counterclockwise positive:

So the second equation we found is:

....(2)
