Thanks, and the reason that I get a greater force is because they spin together with the same ω the torque is also the same on both, but the radius is difference right?
and for chain and sprocket, what do they both have? The tangential force is the same right? but the larger sprocket have a...
Hi guys, I have a question about gear ratio, sprocket or wheel ratio.
So let's say I have a motor with connect to a small output sprocket, and I want to use this motor to pull some load, so in order to do this I need to connect the chain with a larger sprocket, let's say 2 time bigger than...
So, let say I know the radius of the pulley which I will use to pull the object. Let's say we are doing it vertically.
then the torque that I need to overcome the weight of the object will have to be
T = r x mg ?
and with this, what are the other information that I need to obtain in order to...
I only know that the motor is the regular small size 3v DC one, 3mm shaft i believe. Other than the speed of 8300 RPM, the cover of the motor doesn't say anything.
And I googled for the equation for calculating the power or torque of the motor. However, all of them involve either knowin the...
HI guys, I am trying to build a pulley with a gear box.
So I want my pulley, which is operate by a 3V DC motor with max speed of 8300 RPM.
I think the size of the output shaft is 3mm
Ok, so Can someone help me with how to calculate the original amount of torque I can get out of this...
Hi guys, I am wondering about how people make wood claw hammer
a simple one with just a handle, the head, and 1 wedge.
It is fully automatic, let say they have all the parts previously made, and they only need to press a button to assemble all the hammer.
How could the assembly be done...
would the power needed to turn the wheels while stationary be greater than while moving?
of so than using the motor with that much power would be fine.
I just want it to turn, returning isn't necessary.
and I don't get the way you expressed power. since I don't have any idea about the amount of time i want it to rotate. I just want it to be able to turn and stay turned is fine to me.
would it be possible to find the force to over come the...
Homework Statement
I am trying to design a car with simple front rack-and-pinion steering system.
Exactly like this one
I am having trouble find the right motor for the job, assuming typical tire of regular car and the car weight 1ton (included everything)
The shape will be simple...
Hi Walter, thanks for that reply.
The thing is there isn't any specified requirements such as weight and size or speed.
since the person is walking along the side of the car so I assume that it is 5mph.
As for the weight, I am still not sure if that should be calculated given certain...
oh actually, i left this part out
the vehicle is controlled by a hard wired tether from the vehicle to the operator walking along the side of it. The working mechanism of that purpose is not important since we have no knowledge about electricity.
So it is like a toy car with a wired remote...

This is just for a formal engineering report, no product will be made.
