Problem

A master cylinder of area

1\,\text{cm}^{2}

is connected to a slave cylinder of area

30\,\text{cm}^{2}

. If the master cylinder is replaced by another of area

2\,\text{cm}^{2}

while the slave cylinder remains unchanged, the mechanical advantage of the system becomes a) 30 b) 60 c) 15 d) 7.5
