[Music] I'm happy to welcome you to today's episode I'm Toby and as you might've guessed this video is about the tork stepper motors when working on robotics projects sometimes it's quite hard to select the right motor one that is actually useful and does not only lift an arm or attachment but also some payload so how can we measure a rotational force luckily some people already thought it through dating back to Archimedes and his studies about levers fast-forwarding to today nearly every available stepper motor comes with a datasheet that readily tells us the torque of it torque has dimension force times distance and the official SI unit is Newton meter one Newton meter is equal to the torque resulting from force of one Newton applied perpendicularly to the end of moment arm that is one meter long well our scales usually do not measure Newtons so how do you calculate whether a given mo
