A wheelbarrow is a second class lever. In a second class lever, the pivot point is at one end (the wheel), the effort force is at the opposite end (your hands on handles) and the resistive force (load) is in between the two.
The load center of a forklift vehicle has little to do with its lifting capacity; this is determined by its structural engineering including the counterweight and pivot point. The lifting capacity of all forklift vehicles is stated on a tag on the vehicle, and is available from the manufacturer, and is also stated in the operation and safety procedures for the specific vehicle. The load center only tells you where you can place the load on the forks.
Load * Distance ., will act on the CG
Stress testing means increasing the load ,and cheking the performance at each level. Load testing means at a time giving more load by the expectation and checking the performance at that leval. Volume testing means first we have to apply initial load,then at certain time increase the load and check the performance.
A seesaw acts as a force multiplier because it uses the principle of leverage, allowing a smaller force applied at a greater distance from the fulcrum to lift a heavier load positioned closer to the fulcrum. This mechanical advantage is achieved through the seesaw's pivot point, which amplifies the input force based on the ratio of the distances from the fulcrum to the points where the forces are applied. As a result, it enables one person to lift another who may be significantly heavier, demonstrating how the arrangement of forces and distances can enhance lifting capability.
