A second-class lever is a type of simple machine where the load is situated between the fulcrum and the effort. The force applied to move the load is greater than the load itself, providing mechanical advantage. Examples include a wheelbarrow or a nutcracker.
A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.
The location of the effort, load, and fulcrum determine if a lever is a first, second, or third-class lever. In a first-class lever, the fulcrum is between the effort and the load. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.
The main difference between a first class and a second class lever is the relative placement of the effort, load, and fulcrum. In a first class lever, the fulcrum is positioned between the effort and the load. In a second class lever, the load is between the fulcrum and the effort. Examples of first class levers include a seesaw, while examples of second class levers include a wheelbarrow.
I do not believe a Bolt is classified as a lever as it does not have a fulcrum point. If it is, it would depend on what the bolt was being used for. If I had to guess, i would say class three
The main disadvantage of a second-class lever is that it requires a greater force input compared to a first-class lever to move the load. Additionally, the load is located closer to the fulcrum, which can limit the range of motion of the lever.
a second class lever
it is a second class lever
No. It's an example of a Second Class lever.
Answer #1:It is a third class lever.=====================Answer #2:It is a second class lever.

no, its is second class lever.
first class lever second class lever third class lever
Answer #1:It is a third class lever.=====================Answer #2:It is a second class lever.
no,its second class lever for sure....
the law for a second class lever is that the load is between the fulcrum and the effort
Yes, a trolley is considered a second class lever. A hammer is considered a third class lever. Also, a clothes pin is considered a third class lever.
