Witryna29 lip 2024 · There are three different kinds of levers: first class, second class, and third class. Each of these lever classes have unique arrangements of the muscle’s insertion (effort) and bones (lever/arm) around the joint (fulcrum). See the chart below to visualize the difference between the levers: Effort Arm vs. Load Arm Witryna31 mar 2024 · What is the IMA of a lever? Lever. The ideal mechanical advantage (IMA) – ignoring internal friction – of a lever depends on the ratio of the length of the lever arm where the force is applied divided by the length of the lever are that lifts the load. The IMA of a lever can be less than or greater than 1 depending on the class of the lever.
