How fast should the 5-25kg mass accelerate, and what speed should it wind up at.
Your potential energy is weight times elevation. Your 50kg mass weighs around 500N. Your smaller mass will wind up with kinetic energy, which is mass times velocity squared divided by two.

Can you show us a sketch? I am not sure what you want.
In SolidWorks, 2D sketches are attached to a plane. Effectively, you have a plane, and a sketch that is attached to another plane. Try using a 3D sketch. A 3D sketch allows you to attach points and lines at intersections...
Maybe you can specify centre-lines in ISO. In ASME Y14.5, you apply your datum to a feature. You can apply the datum to the feature-of-size dimension. As shown on the drawing, the datum has been applied to the dimension separating the centre-lines of the two tabs. This is totally wrong.
Here in Toronto Canada, it snows, and then they clear the roads. The clearing does not happen instantly. In the meantime, we must deal with the slippery conditions. I cannot image anyone else doing better enough to justify sticking with summer tires.
Datum features B and C are centrelines, not actual features. Datums must be applied to actual features.
The rectangular slots may be used as datum features, but they are features of size. You need to think through how you will fixture to the features. If datum features B and C are applied...
When I read an interesting article on a web site, I check out the home page of the site, and I explore a bit to see what the site is all about. Lots of authors have interesting agendas. Does ChatGPT understand that nothing published on Infowars.com can be trusted?
I like Wikipedia as a source...
Don't ask AI about stuff you are trying to figure out. Ask about things you know about. Work out how accurate it is and to what extent you should trust it.
AI does a good job of recognising sentence structure and jargon. It does not get the facts right, and I wonder about the comprehension.
How to Use ChatGPT to Ruin Your Legal Career
I am an aircraft technology geek, and I have just asked ChatGPT about the Bristol Centaurus engine.
It is fun to go through this thing and pick out mistakes. The engine's displacement was 56 litres. The Avro Shackleton and Supermarine Seafang both...
Brian,
I have recently purchased a new(er) car, and I promised my insurance company I would get winter tires. When I brought the car in, the dealer informed me that my car had all-weather radials, as opposed to all-season radials. All-weather tires are supposed to be effective at clearing...
kaazx9r,
I am confused. Brakes use friction to convert your kinetic energy into heat. Anti-lock brakes prevent locked brakes by applying and releasing them rapidly. Back in the day, we were taught to pump the brakes. In a non-braking event, you are not braking, and anti-lock does not, or at...
LondonNight,
You mention steam. Who is responsible for safety with this thing? Are you qualified? Boilers are an excellent thing to not learn by trial and error.
supergee,
I assume you are discussing Features Of Size (FOS) datums.
There is a crude rule of thumb that your inspection fixture should be ten times as accurate as whatever it is your are measuring. If your datum feature of size is accurate enough, you can ignore its tolerances and material...
Pawan,
Aluminium's galling has been noted above. You can thread aluminium parts into other aluminium parts only if they are anodized. Bare aluminium and chemical conversion filmed aluminium will gall. The parts will not be fully tightened, and you will not be able to take them apart. Been...

Did you claim to be an ISE graduate with two years of IT experience? They hired you anyway.
Factories are massively computerized today. Your employer probably sees useful experience that they will have difficulties teaching. When they explain industrial engineering to you, pay...
Pawan,
Threads in aluminium are weak, which is why thread inserts are used extensively. I am not aware of thread inserts failing in vibration. Read up on fasteners failing under vibration. The website for Bolt Science is a good place to start.
In general, assume that lock washers do not...

I don't know about flatness of sheet metal. Since it is not very rigid, flatness does not really matter.
Sheet metal shops bend at around ±.015", or ±0.4mm. If your hole position is controlled by a bend, your positional tolerance is ⌀.030", or ⌀0.8mm.
I would not think in...
Are you working to ASME Y14.5? Read up on flexible components. You need to specify how your part will be fixtured to control flexibility.
Is your shaft going to run at high speed? Will it be safe? I have not done a lot of power shaft design. You need a certain diameter to transmit the...
grobierno,
Are you constrained for weight? The heavier your dolly is, the harder it will be for it to tip over. Do you have to lift it?
Do your wheels have to be under the dolly? If they are outside, you have a larger footprint, a lower centre of mass, and more stability.
For stiffness...
