Which class is a lever with the fulcrum located between the effort and resistance?

Answers

Answer 1

A class 1 lever has the fulcrum positioned between the effort and resistance, allowing for the amplification of force or the achievement of balance.

The class of lever with the fulcrum located between the effort and resistance is called a class 1 lever. In this type of lever, the fulcrum is positioned in the middle, with the effort applied on one side and the resistance on the other. Class 1 levers are commonly seen in tools such as seesaws and crowbars. They can be used to amplify force or achieve balance. When the effort is applied closer to the fulcrum than the resistance, a mechanical advantage is gained, allowing a smaller effort to move a larger resistance. On the other hand, if the effort is applied farther from the fulcrum, a mechanical disadvantage is created, requiring a larger effort to move a smaller resistance.

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches.

Adaptation: Structural

Explanation: The prehensile tail is a physical feature of monkeys that enables them to manipulate objects and grasp onto branches, aiding in their ability to move through trees.

Moose make mating calls to locate potential mates.

Adaptation: Behavioral

Explanation: Mating calls are a behavioral adaptation employed by moose to attract and communicate with potential mates, increasing their chances of successful reproduction.

Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters.

Adaptation: Structural

Explanation: The thick layer of blubber acts as insulation for whales, providing them with protection against the cold temperatures of the ocean environment.

Humans have five toes on each foot to help them maintain balance.

Adaptation: Structural

Explanation: The presence of five toes on each foot in humans provides structural support and stability, aiding in maintaining balance while walking or standing.

Many birds migrate south for the winter in search of food.

Adaptation: Behavioral

Explanation: Migration is a behavioral adaptation exhibited by many bird species as they move from one region to another, typically during seasonal changes, to find better food sources and suitable habitats.

Behavioral adaptations: Moose's mating calls and birds' migration.
