A $\textbf{hydraulic press}$ for compacting powdered samples has a large cylinder which is 10.0 cm in diameter, and a small cylinder with a diameter of 2.0 cm (Fig. 10$-$51). A lever is attached to the small cylinder as shown. The sample, which is placed on the large cylinder, has an area of 4.0 cm$^2$. What is the pressure on the sample if 320 N is applied to the lever?
