You know when to move on to the next plate or dumbbell when the reps are becoming increasingly easier and there is little to no struggle in finishing them. At this point, you should start with bigger weight and low reps until the same kind of situation repeats its-self. It will also become increasingly easier but you wont see the muscle mass gains as often as you used to
A rating plate will be on the forklift which should tell you the max lift weight, it will lift more but this is very dangerous
it is proven that you can lift your weight or more And you can push nearly 2 times more with your legs!
by being stupid
more weight less reps more weight less reps
You determine the right weight that is perfect for you by guessing and adjusting with what weight you are comfortable beginning with.
yes
Basically they 'curve' the wing, forcing the airflow to lift more weight.
Yes it does. The more weight that there is in the rocket, the more energy it takes to lift off. Its the same as if you raised your hand above your head and it's empty. Put a ten pound weight in it and you have to exert more energy to lift it.
Weight affects lift because as an object gets heavier, it requires more lift force to counteract gravity and stay airborne. This means that a heavier object will need more thrust or a larger wing surface area to generate enough lift to support its weight. Additionally, weight can impact the wing loading and stall speed of an aircraft.
because gravity is pulling the weight down...
Well considering neither actually lift anything, neither.
It allows the vehicle to carry more weight.
