Answer:
![x=8.268 inches](https://tex.z-dn.net/?f=x%3D8.268%20inches)
Step-by-step explanation:
From the question we are told that:
Radius ![r=4.13](https://tex.z-dn.net/?f=r%3D4.13)
Coupler ![C= 5 inches.](https://tex.z-dn.net/?f=C%3D%205%20inches.)
Generally the equation for Stroke in a slider-crank Mechanism x is mathematically given by
![x=2* Radius](https://tex.z-dn.net/?f=x%3D2%2A%20Radius)
![x=2*4.13](https://tex.z-dn.net/?f=x%3D2%2A4.13)
![x=8.268 inches](https://tex.z-dn.net/?f=x%3D8.268%20inches)
