The problem in my packet says, "A medical technician uses a pair of four inch longtweezers to remove a wood sliver from a patient. The technician is applying one pound of squeezing force to the tweezers. If more than 1/5 lb of force is applied to the silver, it will break and become difficult to remove. a. Sketch and annotate the lever system described above. b. What is the actual mechanical advantage of the system? c. Using static equilibrium calculations, calculate how far from the fulcrum the tweezers must be held to avoid damaging the sliver. " I don't understand how this problem can be done or if there is enough information to solve.
