    (d) The lower block of a block and tackle pulley system must be of negligible weight. Solution 18 (a) In a single fixed pulley some effort is wasted in overcoming friction between the strings and the grooves of the pulley; so the effort needed is greater than the load and hence the mechanical advantage is less than the velocity ratio.
