I simply used Hookes law, 100mm initial length, 90mm final length, and a 250lb spring. Does it really matter? I'm really trying to get to the force created by a jack hammer and some values close to the Home Depot jack hammer rating. Could be 600lb, 300 or whatever, but if others area reading...

Interlinking is an old concept, if the front lifts, the weight shifts to the rear, but instead of shifting it to the rear, you have a separate passive hydraulic circuit so whenever the rear compresses, that circuit sends force back to the front to keep the front springs compressed and the car...

Some topics that were similar that I looked at: https://physics.stackexchange.com/questions/175956/good-way-to-compute-the-force-of-a-hammer-blow "For example, if a 5 pound hammer is swung at 50 feet per second, then the kinetic energy of the hammer is 5 * 50 * 50 / 64.32 = 194 foot pounds. If...

All interesting posts, but lets stay on topic, it's just an idea, no one is spending money or trying to market this. We're talking about a vehicle on a smooth surface, taking a turn, no bumps, the turn lasts less than a second or that the amount I need additional load on the tire is less than a...

Right now to make things simple, I’m assuming the tire is infinitely stiff. And even it the tire was soft, the blow should provide some extra load on the tire which is what I want. If the only force the hammer can provide is the weight of the Jack hammer, say 35 lbs, then whats the point of...

I had a followup, so I setup a rig kind of like my leg press, and varied the location where I want to mount my so called jack hammer, basically right near the unsprung part of the suspension seemed the best. What I noticed the rebound of only 25%, so basically the chassis moved up. So from...

thank you all for clearing this up, I may have some followup questions but for now this is great input.

I appreciate the replies, but the quote I posted earlier: "The conservation of linear momentum is not valid in such cases for the impulse applied to the particle by the fixed surface is an external impulse; hence the momentum of the particle is changed but the momentum of the fixed object is not...

That maybe true but what makes me curious is this quote "The conservation of linear momentum is not valid in such cases for the impulse applied to the particle by the fixed surface is an external impulse; hence the momentum of the particle is changed but the momentum of the fixed object is not...

Thank you, to determine reactive forces, what I need to do is setup a pendulum hammer where the end the hammer (handle side) rotates but is also suspended on a spring, then let the hammer swing and drop against the ground, the ground also has a spring on it and measure how much the hammer end...

Thank you, your insights are very helpful.

I guess it depends on where the hammer is acting, on the sprung or un-sprung mass, I believe the dampers will handle the recoil if you’re letting the hammer act on the sprung part of the suspension. Which I don’t want. But you’re right the reaction is what I’m concerned about. If the hammer...

Thank you, this is still different than an active suspension which to me just changes the dampening force but active suspensions, far as I know, put active loads back onto the suspension, all they do is increase the force so the wheel doesn't float off the ground. What I'm asking, during a...

My thoughts are exactly what you guys are posted, that whatever you put on you will put on but what confuses me if I was using a hammer for tampering or breaking concrete there’s no way I would be able to put 600 pounds of static load from each blow from my body weight alone this is what I’m...

Thank you for the fast replies, i thought about the current electro-hydraulic, to my knowledge these systems are to control how the suspensions compresses or rebounds and are faster than regular springs. So I’m guessing what I posted is no different but want can the electro hydraulic systems...

This is just something I was curious about, I'm sure a lot of users here has had some kind of idea related to their field or vehicles in general. I'm not a fully seasoned engineer just a car guy. So be kind. But I wanted to know what would happen if I put a jack hammer system right on the...
