1. The problem statement, all variables and given/known data A 17N spool has an outside radius of 20 cm and an inside radius of 6.4cm as shown. What horizontal force on the rope(wrapped around the inside radius) will be required to pull the spool over an 11cm edge? 2. Relevant equations FdL+/-FdL=0 F=force d=distance to pivot L=perpendicular 3. The attempt at a solution 0.154F-(17)(0.09) F=10N Is this right?
