Explanation:
Answer: With crumple zones at the front and back of most cars, they absorb much of the energy (and force) in a crash by folding in on itself much like an accordion. ... As Newton's second law explains force = Mass x Acceleration this delay reduces the force that drivers and passengers feel in a crash.Sep 30, 2020

Explanation:
A request for proposal is a documentation that invites prospective contractors to submit business opportunities to an agency or corporation interested in procuring a commodities, product, or valuable resource through a bid procedure.
A request for proposal (RFP) is a commercial document that introduces a project, defines it, and invites eligible contractors to compete on its completion.
Answer:
The pressure that the container will start to leak is 154.87 psi
Explanation:
Force on end plates F = p(πR²) ⇒ pπR²
There is an equal reaction from four bolts ∴ F = pπR² / 4 .............. (1)
due to force on bolt, each bolt stretch by 
Therefore;
.........................(2)
Leaking will start when tightening is outstretched by half turn per 16 turns per inch.
Cylinder experience a radial expansion as p increases. it is accompanied by poisson contraction
in axial direction. That is, the bolt do not have to experience a long stretch before the pressure breaks off the plate.
...................... (3)
Axial deformation
of cylinder = L times axial ∈₀
<em>see continuation in attached picture in writing to get the value of Pressure: since we have the value of P</em>
R=8", L=16", t=0.125"
