In this activity, students look at the RNLI’s high-speed Shannon class lifeboats and launch vehicles which use hydraulics as a propulsion system. They explore the relationship between force, pressure and area and how forces are transmitted through liquids. Students also investigate how the output force of a jet propulsion system could be affected by the area of the water jet nozzle and consider the use of hydraulic systems as force multipliers.
