Class Two Lever
Gastrocnemius
The bones that are used during a calf raise is the fibula and tibia. It is more of a muscular movement than a movement of the bones.

The biceps is a class 3 lever
A second class lever is often used to increase force or speed, such as in a wheelbarrow, where the load is in between the fulcrum and the effort. A third class lever is commonly used to increase distance and speed, like in a fishing rod, where the effort is in between the fulcrum and the load.
A class 1 lever is typically used in a beam balance. In this type of lever, the fulcrum is located between the effort (applied force) and the load (object being weighed). This arrangement allows for precise and accurate measurement of weight.
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.
No. A ramp is a ramp, one of several simple machines besides the lever.
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
No, a fork is not a first-class lever. A first-class lever has the fulcrum placed between the effort force and the load, such as a seesaw. A fork is a simple tool used for picking up and eating food, and does not function as a lever in the traditional mechanical sense.
The ideal mechanical advantage (IMA) of a first-class lever is 1. This means that the input force and output force are equal in magnitude for a first-class lever. The lever is used to change the direction of the input force rather than to magnify force.
An oar is a class 3 lever. This is because the oar, like all class 3 levers, is not used to reduce the force needed to move the load, but is used to increase the amount of travel of the load.
