Problem

A workshop press uses a small piston of area

3.0\,\text{cm}^2

. The operator can exert up to

600\,\text{N}

on it. The fluid and cylinder are designed to withstand a maximum pressure of

2.5\times10^{5}\,\text{Pa}

. If the large piston diameter cannot exceed

20\,\text{cm}

, the greatest load that can be safely lifted is closest to a)

6.1\,\text{kN}

7.8\,\text{kN}

2.0\,\text{kN}

31\,\text{kN}
