we all know that T = F x r where r is prependicular distance from axis of rotation. Greater the distance greater will be torque and hence greater angular acceleration for same moment of inertia(i.e same material and axis) Now, consider a wooden board pivoted at one end. The wooden board is rotated with the help of a motor where it is pivoted. Now we switch on the motor (such that it moves with constant rpm), place a block of considerable weight on the board when it is horizontal, ofcourse the block will fly away like thrown from catapult. Now far the block is placed from pivot, greater the distance it will cover when thrown. This shows that it has greatest acceleration when at max distance from center. This shows max force would have been applied to it by the board when it is at max distance from pivot point. But according to above formula, for constant torque force varies inversely to distance from center. That means as we go away from fulcrum or the pivot point, less force should be applied to the block (since motor runs at constant rpm) but practically it is not so, far the block is placed far it is thrown. Can anyone explain???
