Solve the following tasks according to the general principles. That is, draw free-form images for each task from which you calculate support reactions. Then cut the part appropriately, draw a free image of the cut part, calculate the loads on the cut cross-section and the quantities desired in the task.
When the force P acts, an elongation of 1800𝜇𝜇 (1800 x 10-6) is caused on the rods (2). How much does the point of application of the force shift and what is the elongation in the rod (1)?
Length of ABC is unknown.
Given, As shown in the figure, the rods (2), (1) and (2) are in parallel.  As the rods are in parallel, the deflection in the bars are same no matter the length, Area and Youngs Modulu ... See the full answer
