Compressive forces of weight will be much less on the Moon.
Contact forces in the event of a collision with an obstacle will be similar (at similar speeds). If the rover was less strong then this certainly implies that a collision at similar speeds would do more damage to the rover than a similar collision would do to a stronger Earth-based rover. Interestingly the linked article describes avoiding obstacles as one of the biggest challenges of driving the rover on the Moon. The working to show what the typical forces involved in small bumps, how they compare in magnitude with the weight forces and what kind of collision would be expected to reach the strength limit of the rover seems to be missing. |

In no way at all does this support a faked landing.
If L_D is correct that the vehicles were not strong enough to operate on the Moon, then by his own claim they were not strong enough to operate on Earth. There is footage of the lunar rovers operating so obviously they worked somewhere. If it was faked then the vehicles would have to be stronger than claimed so they could operate on Earth. A vehicle strong enough to operate on Earth would have no problems operating on the moon. So it would seem that the only two real options are: L_D’s understanding of physics is wrong. The claim that the rovers could not work on Earth is wrong. |

Still with one astronaut only taking it to about 863 lb. The performance must be staggering for 1 hp electric motors and only 150lbs? HOLD ON TO YOUR HATS LADIES! BTW, 1 hp is actually quite a low powered mobility wheelchair, they can come in up to 3hp. |

863lbs is still a shirtload for 1 hp, I don't have youtube on this computer but from memory there is footage of two astronauts in the rover (taken from the rover camera) and by all accounts the rovers performed well fully loaded. |
