I know to work out mechanical advantage it is load/effort but some how I still got the question wrong. The question is; a jack requires an input of 37N to raise a load of 175Kg. If the distance moved by the effort is 7m and the load is raised through a distance of 7mm, find; Mechanical advantage, velocity ratio, efficiency and work done.
mechanical advantage? Watch
