1. The problem statement, all variables and given/known data A ruler of 0.75N and 52.0cm is supported 1.0cm from each of its two ends. A weight of 1.00N is placed 16.0cm from the left end of the ruler. Determine the forces acting upon the ruler at the two supports. 2. Relevant equations I know that the two forces of the supports are pointing upward and 1.00N is pointing downward as well as 0.75N. So I know that the two forces of the supports together are 1.75N. But I don't know what to do now.
