The tools shown in the diagram are used for gardening. Each is made up of two levers that are attached to each other. The handles are the input arms
and the cutting blades are the output arms.
Hand shears
Lopper
Which tool has a greater mechanical advantage and why?
The lopper, because its longer handles produce more output force with less input force.
The hand shears, because you can apply less force to the handles with one hand,
The lopper, because the input work is the same as the output work.
O The hand shears, because their shorter handles transfer force more quickly to the cutting blade.
