Question
When a force of 2 lb is applied to the handles of the brad squeezer, it pulls in the smooth rod $A B .$ Determine the force $\mathbf{P}$ exerted on each of the smooth brads at $C$ and $D$.
Step 1
We can do this by taking moments about the point A and setting it equal to zero. This gives us the equation: \[ -F_{AB} \cdot 1 + 2 \cdot 2 + 0.25 \cdot 0 = 0 \] Solving this equation gives us: \[ F_{AB} = 4.5 \, lb \] Show more…

The nail cutter consists of the handle and the two cutting blades. Assuming the blades are pin connected at $B$ and the surface at $D$ is smooth, determine the normal force on the fingernail when a force of 1 lb is applied to the handles as shown. The pin $A C$ slides through a smooth hole at $A$ and is attached to the bottom member at $C$
