1.	Draw a simple diagram ofafire tongs and mark on it the fulcrum F and the points of application of load L and effort E. (a) Name the class of lever. (b) if load arm is 15 cm and effort arm is 5 cm. what is its mechanical adavantage?
Answer» Solution :(a) FIGURE shows a fire tongs in which the effort E is in between the load L and fulcrum F. this belongs to class III levers. (b) Given: load arm=15 CM, effort arm=5cm Mechanical advantage=`("effort arm")/("load arm")=(5)/(15)=(1)/(3)`.
