    Calculation Torque
AI Thread Summary
The discussion revolves around calculating the torque required to rotate a 500 kg load using a handwheel setup. The initial torque calculation provided is 2800 Nm, based on the formula Torque = force x per. distance x coefficient of friction. However, there are concerns about the appropriateness of the coefficient of friction used and the actual setup depicted in the attached image, which does not clearly represent a handwheel. Further clarification on the setup is suggested to provide more accurate assistance. The conversation emphasizes the need for precise details to ensure correct torque calculations.

Hi team
In my one of the application I have to use the gear box to rotate 500 kg load
I have to use handwheel to rotate
I am using the formula
Torque= force x per. Distance x coefficient of friction
= 500x.7x.8 : 2800 Nm
Is it correct to calculate the torque
I have attached the image for clarity could you please help

Thanks in advance
Regards
Raj

Your use of coefficient of friction seems incorrect. Moreover you have mentioned that a hand-wheel would be used for rotation but the figure shows something far different from a hand-wheel setup. If you can sketch the actual setup, take a pic of it and post it then it will be easier to answer your question.

Hi Benny
Thanks for your reply
I have attached the image for your understanding
The gearbox is mounted to a block
The block has a guide rod and that swivels when gearbox is operated
The gearbox is a double reduction gearbox

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
