Average shear stress in going between a spliced rod?

  1. Jan 28, 2014 #1
    Problem statement:
    Two 3/4-in.-diameter nylon rods are spliced together by gluing a 2-in. section of plastic pipe over the rod ends, as shown in the figure. If a tensile force of P = 500 lb is applied to the spliced nylon rod, what is the average shear stress in the glue going between the pipe and rods?


    I need help with this problem. I know that {average shear stress} = {force} / {area}. But I am very confused when you take into account this splicing! Thank you in advance!

    Can you articulate in words what's happening here? For example, what forces are acting on each of the two rods (treated as free bodies)? What is the glue doing?

    I'm assuming there's some adhesive force acting on the rods, as well as P?? But I'm not sure...
