How did you find PF?: web search. I am new to all this. There was another post similar to this, but it was above my current education. I didn't go beyond 8th grade. So, beyond that I learn by doing, and through other friends. I'm constructing a building on wheels for pastured... Read more ..read more

Hi, I wonder if someone can help with the following problem? We have a sealed box in space and inside the box is an electric motor with the stator attached to the box. The rotor arm is attached to the inner race of a bearing and the outer race of the bearing is also attached to the box. There... Read more ..read more

Need some help. Trying to lift a 10 lb box 20 feet. Hydraulic motor driven. Bucket attached to chain anchors on each end of the chain. 6” diameter sprocket on top and bottom, the bottom sprocket will be driven by a hydraulic motor. How much torque does the hydraulic motor need? Weight of chain... Read more ..read more

I'll try and keep this as easy as I can. The Right Triangle above represents the forces acting through the trailing shoe of a automotive drum brake. Point A is the central position of the brake expander. When the foot brake is depressed, a force is created that pushes the brake... Read more ..read more

I have an encoder that measures the rotational angle of a shaft. The problem is that the other end of the shaft can move in X and Y (forward/backward and left/right) as well as rotate. Assuming I can get couplings to link the shaft to the encoder and the moving item, will the encoder always... Read more ..read more

In the current project, I need to convert rotational motion into linear motion using a crank and slider mechanism. The project requires the linear movement to range from 7 cm to 15 cm. Additionally, the system should allow for manual adjustment of the height, so the linear motion can oscillate... Read more ..read more

For context, I'm developing a submarine simulator with a heavy focus on realism, especially on the physics side of things. I've already implemented a fairly accurate linear drag model for forward/backward and rise/dive movements, but I'm not sure where to start with calculating the rotational... Read more ..read more

Hi friends. Nice to be a new member of that forum. Content and member knowledge are impressive. I was reading a lot about fan types and airflow physics when pulling and pushing air. My main idea is to do some test with different configurations of my setup. I'm going to measure temperature in... Read more ..read more
