Only a very small force if the arm only has to be supported.

What other weights do the arm carry and at what angle does the biceps attach to the fore-arm?

What is the distance to the hand from the fulcrum and what is the arm weight (assuming a weight is in the hand and arm weight has to be added to the weight-in-hand)?

The length of the hand to fulcrum is also required.

There is no such thing as 90% angle: 90 degrees perhaps?

What are the load effort force and the fulcrum in a biceps muscle?

In the biceps muscle, the load is the weight or resistance being lifted, such as a dumbbell. The effort force is generated by the muscle itself to lift the load. The fulcrum is the point in the body where the muscle attaches and pivots to create movement.

Is your arm a first class lever?

Yes, the human arm is a third class lever. The biceps and triceps act as the effort and the load, with the elbow joint acting as the fulcrum.


What type of lever do biceps make when they contract to lift a load in the hand?

The biceps muscle functions as a third-class lever when it contracts to lift a load in the hand. In this type of lever, the effort force (biceps) is applied between the fulcrum (elbow joint) and the load (hand weight). Third-class levers are optimized for speed and range of motion rather than force.


Why is the elbow considered a third class lever?

The elbow is considered a third class lever because the effort force is applied between the load (resistance) and the fulcrum. In this case, the biceps muscle (effort force) exerts force between the hand (load) and the joint of the elbow (fulcrum) to produce movement.
