WebDec 21, 2024 · That means the torque in A is $94.5Nm$ and the torque in B is $4.5Nm$. We divide both by 2 since there are actually 4 screws, not 2 and arrive to $47.25Nm$ and $2.25Nm$ Since A is a bigger torque, we wanted to look for a drywall anchor that can support that torque, but I have the feeling we did something wrong and I can't see it. WebTorque is defined as the twisting force exerted by the drive unit on the conveyor screw. Torque is transmitted through the drive shaft of the drive unit to the screw and converted to force to convey the bulk material. Properly selecting screw conveyor components is important to minimizing downtime and maintenance. lightshow critters-bite.us
