Average shear stress in going between a spliced rod?

AI Thread Summary
The discussion revolves around calculating the average shear stress in glue used to splice two nylon rods under a tensile force of 500 lb. The formula for average shear stress is acknowledged as force divided by area, but participants express confusion regarding the implications of the splicing on this calculation. Key considerations include the forces acting on each rod and the role of the glue in transferring these forces. Clarification is sought on how to effectively analyze the system as free bodies. The conversation highlights the complexities involved in understanding shear stress in spliced components.

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...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
