Question picture: My solution: Where: S is the lineforce Ff is the force as a result of friction a is the resulting acceleration F is the acting force The answear is supposed to be a=(F-2mg(mu))/(m+M) Any idea what i could have missed? Thanks for your help on beforehand!

I'm building an aluminum tandem axle (7k total capacity) trailer. Boat (18'/1300#) on the rear and a Ryker Can Am 3 wheel (750#) on the front. It's a 23'-6" x 6'-8" bed. Max live load will be approx 2250#. 900# frame weight. 230# axles. I'm testing beam sizes with online calculators and need...

I thought this was a common thing but it turns out there's virtually no such thing. I just bought a utility trailer (along with my boat trailer, I now have a fleet!) https://www.lowes.ca/product/trailers/carry-on-trailer-2000-lbs-gvwr-3-ft-6-in-x-5-ft-wire-mesh-utility-trailer-253168 is tiny -...

New trailer and new self built boat. Need confirmation of my calculation for placement of boat on trailer to have the correct tongue weight. For those not familiar with trailers: The tongue of a trailer is the forward beam that has the female ball receiver at the front end. It is imperative...

Hello, i´ve got a problem with the calculation of the forces on the hitch of a vehicle and a trailer. I do need the lateral force on the hitch for the calculation of my single track model of the vehicle and trailer. I have a longitudinal model of the vehicle and the trailer. My input signal...

I have a trailer that is aproximately 12 feet by 5 feet wide. I would like to design a way to be able to unload 1 to 2 tons of gravel. (This is not a dump bed). I would also like to be able to unload 1 ton of hot asphalt. One idea is to make one of those hand crank unloaders that you can buy for...

Hello! This is my first post here, and I look forward to many more! This is a sort of riddle I was told today, and left me full of doubts. So, the 'puzzle' was the following: " There's a man carrying behind his truck an enclosed trailer full of birds inside it. All the birds are standing on...

If I am towing a 10,000 lb. trailer downhill on a 6% grade at 65 mph and I hit the brakes coming to a complete stop in about 5 seconds, how much force is being applied to the trailer hitch? I am trying to build my own hitch and the forces applied will help me determine plate thickness. I will...

Hello, I have an problem with mathematical modelling of a special kind of articulated trailer (please have a look at the images: 1st image is the yaw plane and the second is the ZX plane). I have two methods of deriving equations of motion namely Lagrange and Newton-euler to analyse their...

Here's a link to a trailer manufacturer, and their claims of which style of lift/tilt system is best on a trailer... http://bigtextrailers.com/hoist-comparison/ I have a very hard time seeing how the 2 ram system is inferior to the single ram system especially.. assuming build quality is equal...

I want to do an investigation on how the damping of a trailer when it is moved horizontally. I saw a video of a toy car with a trailer and someone changing the weight distribution on the trailer. This change led to a big difference in the oscillation patterns of the trailer when moved. (the...

I am a trucker. I pull 53' dry van trailers with a big rig truck (a tractor). When a tractor-trailer backs straight backwards (not turning ) it is called straight line backing. Probably most people here know from backing boat trailers or other trailers at some point in their lives that when...

So I was reading about Tesla's plan for battery swapping. I didn't think that was such a great idea, since you would be leaving behind something that was a good fraction of the cost of the car. Might there be a better way?: So, it's the future: You've been driving around town, and used up...

I need a little help on the redesign of our boat trailer, if you guys wouldn't mind giving a little advice. We have a heavy boat [we can assume the boat is 20,000 lbs], and we need to 1] increase the capacity of our axles, and 2] redistribute the loading of the weight. Currently, the weight of...

So I just got out of college and have about 15k or so saved up. My job pays me about 65 k a year. I have no debt and own my car. I'm most likely going to move out of my parents house in a few months. I think it would be best not to buy a house for at least another decade, maybe two, and take out...

I had a somewhat unnerving experience recently. I had bought a travel trailer (caravan for UK readers) and was towing it home when it started to sway from side to side. The oscillations built up to an extreme amplitude of 90 degrees, limited by the trailer hitting the side of the tow vehicle. I...

https://www.youtube.com/watch?v=QAEkuVgt6Aw I saw this trailer on ultra screen in 3d and I was captivated. No doubt a very well made trailer, but still I'm pretty stoked for the movie! Even if it just reaches the success of the first, it's been a nice series reboot.

https://www.youtube.com/watch?v=vP0cUBi4hwE Loved the book, but the trailer looks terrible. From what I can tell it will suffer a similar fate as the Hunger Games in the sense that the magic of the book was the interesting internal dialogue and complex moral issues (also in Dune). Internal...
