Center of Mass of Truck with weights added

AI Thread Summary
The distance between the front and rear wheels of the truck is 3.50m, with initial upward forces of 12300N on the front wheels and 9180N on the rear wheels. After adding a 4850N object to the tailgate, located 4.23m from the front wheels, the new upward forces on the front and rear wheels need to be recalculated. Additionally, the maximum weight that can be added to the tailgate without tipping the truck must be determined, ensuring the front wheels do not rise. Accurate calculations are essential for maintaining stability and safety when loading the truck.

distance between front and rear wheels of the truck is 3.50m. total upward force on front wheels is 12300N and rear wheels is 9180N. (I have already calculated that the center of mass is 1.28 m behind the front wheels).

Now a 4850N object is added to the tailgate 4.23m from the front wheels (assuming the truck can hold it). how much force is now pushing upwards on the front wheels and the back wheels (individually, not total)


b) what is the maximum weight that can be added to the tailgate without causing the truck to tip (front wheels rising)

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds?

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
