A fulcrum dividesa crowbar into ratio of 1:3. What weight will be lift

1.	A fulcrum dividesa crowbar into ratio of 1:3. What weight will be lifted if an effort of 100 n is applied at the end of longer arm ?
Answer» ght that can be lifted by an effort of 100 N at longer SIDE will be 300 NExplanation :ratio of shorter arm: longer arm = 1 : 3=> LOAD arm : Effort arm = 1 : 3we know that ,LOAD/ Effort = Effort arm : Load arm=> load/100 = 3 : 1=> load = 300 NHence the weight that can be lifted by an effort of 100 N at longer side will be 300 N
