how to sign the word aeromechanics

To sign “aeromechanics,” use the American Sign Language (ASL) sign for “air” by forming a “C” with your dominant hand and moving it in a circular motion around your head, then use the sign for “mechanics” by making a fist with your dominant hand and placing it on your other forearm, then twisting your wrist in a circular motion. Combine the two signs together to represent the word “aeromechanics.”
