When you measure the depression you measure the vertical displacement from equilibrium. This is done with a vertical ruler in the middle of the rod.

i was talking about the 3b question. should the 100 g placed closer to fulcrum to balance the fuclrum as
A.C.M=C.M
so 100*x=55.5 * 20
thus x=(55.5*20)/100=11.1 cm
so the 100g must be placed at like 1 division right?

SHOOT ME!!!!!            \N QGHTBV

SHOOT ME AGAIN!!!!!!

You are right I thought the 100g and 55g mass were the other way round.

sweetsh:

emi:
so where should the 100g be placed ?
