Average shear stress in going between a spliced rod?

Click For Summary
SUMMARY

The discussion centers on calculating the average shear stress in glue used to splice two 3/4-inch diameter nylon rods under a tensile force of 500 lb. The formula for average shear stress is defined as shear stress = force / area. Participants express confusion regarding the impact of splicing on the calculation, particularly in determining the effective area of the glue joint. Clarification is sought on the forces acting on the rods and the role of the adhesive in this scenario.

PREREQUISITES
  • Understanding of shear stress calculations
  • Familiarity with tensile forces and their effects on materials
  • Knowledge of adhesive bonding principles
  • Basic mechanics of materials, particularly free body diagrams
NEXT STEPS
  • Study the mechanics of adhesive bonding in engineering applications
  • Learn about free body diagram analysis for composite structures
  • Research the properties of nylon and its behavior under tensile stress
  • Explore shear stress distribution in glued joints
USEFUL FOR

Mechanical engineers, materials scientists, and students studying mechanics of materials or adhesive bonding techniques.

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...
