Final answer:
The three supports in question provide a supporting force, tension force, and thrust force.
Step-by-step explanation:
The three supports in question provide different types of forces.
The first support, which is a surface, applies a supporting force to the object to support the weight of the object. This force acts in the upward direction to counteract the force of gravity pulling the object downward.
The second support applies a tension force along a stretched flexible connector, such as a rope or cable. This force acts in the direction of the connector.
The third support provides a thrust force that pushes the object forward in response to a backward force. This force acts in the direction opposite to the backward force.
