# Drop impulse shock wave

## Drop impulse shock wave

(OP)
Hi,

I wasn't sure where to post this but since there are shock waves involved I thought i would start here although it may be more of a physics question. I am doing some trigger design on a paintball gun and want to try and do some rough drop scenario calculations. The main component a am trying to evaluate is the trigger sear and how high i would need to drop the gun before the sear spring was overcome.

The sear coming unlatched under its own inertia seems easy enough to evaluate - I seeing if the kinetic energy of the latch just before impact has enough to over come the elastic potential energy of the spring hold it in place (plus friction work). Anyway i am wondering if there is another scenario where the sear is kicked out from an impact traveling through the body of the gun. For simplification I am think of just two bodies - the body of the gun and the sear. The two objects travel at the same velocity until impact. The two object are couple through a pivot pin and the sear contact face. First of all would it be conceivable that the shock wave could impart energy through the sear face contact face and knock the sear out of place?

Secondly would it possible that the shock wave could transfer more energy to the sear body than it actually had in the form of kinetic energy before impact. Basically is an shock wave through the gun the worst case scenario or the inertia case described above?

If the shock wave scenario then how i could start to evaluate it.

Any help would be greatly appreciated.
Will

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why itâ€™s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
