.......Does not compute.....
How strong are you? Do you grip it by the shaft or a big pulley? Is it smooth or not?
Actually even if you answered these, it would not be possible to guide you to evaluate torque with your hand to any meaningful accuracy. If I need to know, I use a fishing scale, a rope, a pulley and a calculator. A very crude measuring method, but beats my hand by a mile. Measure the radius of your pulley, make several turns around it with the rope and measure the pull with the scales. Use the calculator to convert from the radius of your pulley to meters if you want metric result or foot/inch if you prefer what many with your address does.
You can also do just one turn around the pulley with your rope and use it as a "clutch" to get an approximation of stall torque. Tighten the rope and read the scale just before motor stalls. Any pull you do at the end of the rope will add to the inaccuracy, so use as many turns as necessary to minimize it. |
