study movement cart

Forgive my ignorance in motion: eek: the photo has cleared me ideas!!!
Therefore if the fork is not horizontal you must try to estimate a maximum inclination and verify that the direction of force does not exceed the fulcrum.

In my opinion it is completely wrong your way of force that changes angle. is a weight force, and the team is mobile (not rigid). if for that it is not even 60% of the entire weight that you download behind, but it is a plausible estimate. a cube leaning on a tilted plane having mass m will give a parallel reaction and a perpendicular to the plane. but if this plan is bound to one point it has that the result is only one downward and is m*g. the parallel and perpendicular forces are internal forces, like those of friction between piece and team...so they do not look because they are not part of the external system.
the only way to know how much vertical force there is on the pin is to put a balance. the rest is all estimated not real theory.

1) you have to break down your strength and see the fy how much it is worth compared to the fx if you want but are not talking about strength given by a mechanical component but weight force (see point 3)

2) if the inclination is on the other side what happens? is it more advantageous?

3) the transmission of weight strength is towards the always vertical floor, so you can put the plate to the turn as much as you want but the force is transmitted to a pin. the team at l could have any form and angle. the weight force follows the direction of the gravitational acceleration vector

about my post #21 schematic place. There are no inclined forces. we are on a free circular pin, i.e. zipper pin.

I would like to consider all your ideas and advice. ..however I received shortly ago the photo of a user of the motorcycle forum who made the shopping cart in question, using nottolini instead of the teams.

but you can put what you want, straight, swinging pins on bar, nottolini as long as you don't fall off your bike.

that at this hour we had made 10 already welded and painted... It is not so difficult :biggrin::biggrin:

:smile: you are right!!! next week I go to buy the tubular and then in the time cutouts I begin to compose!!! and then what do you want to cost 2 linear meters of tubular?! if even it didn't go well to the maximum I do it again... I hope only that you don't ask me a fortune the welder...that is my babbo!!!!! :hahahah:

hahahah 2 meters do not know if you sell them, I usually take 6 meters (also for private use) cmq a couple of meters depends on the weight but you are on 10/15 euros. the welder... well a good bottle of wine and you are affixed :biggrin: well from 20 €/hour.

in all you will cost to span a 150 euro finished painted and the wheels ... even less.
cost estimate:
- iron 15 euro
- 4 wheels 30 euro
- bomboletta bottom + bomboletta color 10 euro
- labour of babble 2 x 30 = 60 euro
- your labor to mount all 1 x 30 euro
- forfait crops and pins 5 euro
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
total = 150 euro -
labour = 90 euro
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
total living expenses = 60 eurobut at the end of the simulation, did you see that it was the subject of the post? I put the video and image of my model in motion.

in fact the majority of companies sell the rods from 6mt while I found a blacksmith/allfare that treats both the old and the new...I already bought from him... cut the iron to the extent you want and sell it to weight

I still didn't put my hands on solidworks because today I had the pc engaged in a somewhat expensive rendering of resources and I didn't want to weigh even more the pc... I saw the video and thank you for the interest. . .after morning I do some tests and then place the results... beyond the realization of the cart is a way to learn new things

beyond the realization of the cart is a way to learn new things

:finger: it is not the cart itself but:

- you learn to make measurements
- you learn to use motion
- you learn to make static fem
