(2)

 

The small piston of a hydraulic lift (see figure below) has a cross-sectional area of \( 3.10 \mathrm{~cm}^{2} \), and its large piston has a cross-sectional area of 198 \( \mathrm{cm}^{2} \). What downward force of magnitude \( F_{1} \) must be applied to the small piston for the lift to raise a load whose weight is \( F_{\mathrm{g}}=15.6 \mathrm{kN} \) ?
