Explanation:

Question 20

The load center is defined as the distance from the center of gravity of the load to the face of the forks. Option a is about load end to fork face, not center of gravity. Option b is about mast to operator's compartment, irrelevant. Option c is about load's center of gravity to steer axle, not correct. So option d matches the definition.

A lift truck's center of gravity changes based on load, lift height, mast tilt, etc. So the statement "The lift truck center of gravity always stays in the same place" is false.

The Stability Triangle of a lift truck has three supporting points: the center point of the steer axle, and the center points of the left and right drive tires (or the two drive tires' contact points, but the center point of the drive axle is not a supporting point). So option a is a supporting point, options b and d (left and right drive tires) are part of the drive axle's contact, but option c (center point of drive axle) is not a supporting point.

Answer:

d. The distance from the center of gravity of the load to the face of the forks
