When does a lever act as a class III lever?Question 15Select one:a.Load is between fulcrum and effortb.There is no class III leverc.Fulcrum is between effort and loadd.Effort is between fulcrum and load

In which type of lever is the effort situated between the load and the fulcrum?Question 11Select one:a.Second-class leverb.Fixed pulleyc.First-class leverd.Third-class lever

While researching a topic, a student has taken thefollowing notes:• A lever is a simple machine consisting of a rigidbeam and a fulcrum.• The fulcrum is the point about which the beampivots.• The input force (effort) is the force applied to thelever.• The output force (load) is the force that the leverexerts on another object.• In first-class levers, the fulcrum is located betweenthe effort and the load.• In second-class levers, the load is located betweenthe effort and the fulcrum.The student wants to contrast first-class levers andsecond-class levers. Which choice most effectivelyuses relevant information from the notes toaccomplish this goal?A) In levers, the effort is the force applied to thelever; the load, in contrast, is the force that thelever exerts on another object.B) In first-class and second-class levers, the fulcrumand the load are in different locations.C) First-class levers are simple machines consistingof a rigid beam and a fulcrum, but then again,the same is true of second-class levers.D) In first-class levers, the fulcrum is locatedbetween the effort and the load, but insecond-class levers, the load is located betweenthe effort and the fulcrum.

In first-class lever the load is located at some point between the effort and the fulcrum.Question 7Answera.Trueb.False

Which of the following statements describes a second-class lever?Question 7Answera.There are two input forces used to create a mechanical advantage ratio greater than 1b.The fulcrum is positioned between the input force and the loadc.The input force is positioned between the fulcrum and the loadd.The load is positioned between the input force and the fulcrum

What is the mechanical advantage of a lever defined as?Question 6Select one:a.Effort/loadb.Load/fulcrumc.Fulcrum/effortd.Load/effort
