2. From product production to shipment, every detail is strictly controlled. The product has been pushed and tested.
3,The hammerhead and the handle are very firm and will never drag.
A hammer is a knock on an object that moves or deforms it. Most commonly used to hammer a nail, correct or to knock the object open. The hammer has a variety of forms, and the common form is a handle and top. The top side is flat for percussion and the other is hammerhead. The shape of the hammerhead can be shaped like a horn or a wedge, and its function is to pull out the nail. There are also round head nails.
In the use of lever, in order to save energy, the lever with the power arm should be used. If you want to save distance, you should use a lever that is short of the lever arm. So you can use leverage to save energy, you can also save distance. However, to save effort, you must move more distance. If you want to travel less, you have to work harder. It is impossible to save effort without moving the distance. It is from these axioms that, on the basis of the theory of gravity, Archimedes discovered the principle of leverage, that is, the distance from the fulcrum is inversely proportional to the weight of the two weights.
The fulcrum of the lever does not have to be in the middle, to satisfy the following three points of the system, basically is the lever: fulcrum, the force point, the stress point.
The formula is written like this: the power x power arm = the resistance arm, which is F1 times l1=F2 times l2, which is a lever.
Power arm extension
Leverage also has a labor-saving lever and a demanding lever, both of which have different functions. For example, there is a punching machine with foot, or a juicer pressed by hand. Moment); But we're going to press the larger distance, and the force is only going to be smaller. There is also an arduous lever. For example, the crane on the side of the road, the hook of the fishing line is at the tip of the whole rod, the tail end is the fulcrum, and the middle is the hydraulic press (torque > This is the hard lever, but the hard work is to get the center point to move a little distance, and the tip of the hook will move a considerable distance.
Both types of leverage are useful, but the area to be evaluated is to save effort or to save movement. There is also something called a wheel shaft, which can also be used as a lever, but the performance can sometimes be added to the calculation of rotation.
