here u go !! i am explaining it !! on the right hand side the force was 4 N and distance from pivot 2 cm so the moment becomes 0.08 Nm acting downwards !! ok ?

plus i don't remember the force nd distance on the left buh i remember that the moment was 0.18 action downwards , which means that the rod would tilt 0.10 moments downwards ... to balance it we needed to bring it up by 0.10 Nm !! the force X acting upwards was 2 cm from the pivot , means 0.02 m so if the force is 5 N the moment will be 0.10 Nm and the rod would now be in equillibrium as the sum of anticlockwise moment will = clockwise moment :)


so now whats the reward for the bet ?? we are 4 ppl waiting :D hahaha !!:cautious:
