Answer:
a)true
Step-by-step explanation:
The levers are devices specially designed for the person who handles it to exert less force, although it must make a greater displacement, which is very useful when it is required to lift a load.
The principle of mechanical advantage is the relationship between the force exerted on an object and the force applied by a person, so if it is greater than 1, the lever produces more force, but less speed or distance, than the force exerted on he. If the mechanical advantage is less than 1.0, the lever produces more speed or distance, but less force, than the input.
