I think truck A will be the truck that will tip over.  I think this because the center of gravity is so close to the edge.  Also because if you draw a straight line down from the center point it will no longer be on the truck.  I think that the most stable truck is truck C becausue its more center when you draw the line down and it will keep it balanced.

I think truck A will tip over. It will tip over because if you draw a line down the center it is not on the center of gravity.

Truck A will be the truck to tip over becasue it's center of gravitiy is outside of the truck. If  you were to draw a straight line down the dot would be outside the tires, which means the truck is unstable.

I think truck A will tip over because the ground is slanted down towards the left. Truck A's center of gravity is also towards the left of the truck, meaning that there is little to nothing balancing it on the right side.

i think truck A will tip over because it's center of gravity is towards the bottom left along the slope, so the truck's weight is leaning all to that side causing the truck's right side to lift of the ground where there is no support.

i think that truck A and truck B will not tip over because the both have a low center of gravity and i believe that truck C will tip over because it is very top heavy with a high center of gravity.

I think that truck A would tip because the truck gos over the center of gravity

I think truck C will tip over

I think that truck A will tip over because the truck goes over the center of gravity.

truck a will tip over because of the center of gravity has a lower location.

i believe that truck A will tip over.  This is because its center of gravity is not aligned with its base of support.  Trucks B and C, although they look unstable, are fine because their centers of gravity are in line with the base of their supports

I think Truck A will tip over. That's the only answer that makes sense to me because Truck A's center of gravity is the closest to the ground, and is on the bottom-left.

Truck A will be the first to tip over because it's center of gravity is not in line with the supporter. The truck is leaning towards the left so is the center of gravity which will result in the truck tipping over.

Truck A will tip over because if a line is draw from the center of gravity straight down, it looks closets to going into another base, a sign that it will fall.
