On a telehandler that is not equipped with stabilizers, which is not one of the three supporting points of a stability triangle?

The stability triangle is a crucial concept in telehandler operation, defining the area formed by the three points of contact that provide balance. For a telehandler without stabilizers, the three supporting points typically include the rear axle's center point and the two front tires.

The center point on the rear axle contributes to the stability triangle by serving as a base point, while the left and right front tires represent the other two points. This configuration allows the machine to maintain stability while lifting and maneuvering.

The left rear tire does not form part of the stability triangle because it is not one of the points of contact supporting the telehandler in a stable position. Instead, only the front tires and the center rear point contribute to maintaining balance, making this the correct response in relation to the mechanics of telehandler stability.
