Specify the required torque M on the power screw necessary to overcome a resistance of 490 N to motion of the carriage along its horizontal ways. The screw has a mean diameter of 21 mm and has two separate square threads which move the carriage 16 mm per revolution of the screw. The coefficient of friction may be taken as 0.15. Bearing Answer: M = i Bearing N.m
