  1. Question: I need to work out the torque required for a motor to move a block around a point. The point has been labelled in the diagram. The points of friction will be two deep grove ball bearing, which hold the rod which support the block above. The block's mass is: 4.514kg Dimensions of the block are: 0.3 (W) x 0.3 (D) x 0.25 (H) The final velocity of the block when moving is: 0.01375 m/s It's average acceleration is: 0.00172 m/s2 The co-efficient of friction of the bearing is 0.0015 The distance the block will move is 0.11m Ive tried various torque calculation but they don't seem to apply perfectly to this system, Any help would be greatly appreciated. Thanks, Tristan
