Question

A medical technician uses a pair of four inch long tweezers to remove a wood sliver from

a patient. The technician is applying 1 lb of squeezing force to the tweezers. If more than

1/5 lb of force is applied to the sliver, it will break and become difficult to remove. Assume

the squeezing force is applied at 90 degrees to the tweezers.

a. Sketch and annotate the lever system described above

b.Using static equilibrium calculations, calculate how far from the fulcrum the tweezers

must be held to avoid damaging the sliver.

c. What is the mechanical advantage of the system?

d. what class of lever is the system?
