A force meter, also known as a Newton meter, is a tool for measuring the amount of Newtons a force is. (Forces are measured in Newtons.) It consists of a tube with measures on the side and a spring with a hook on the end. You place a weight on the hook and the spring will stretch accordingly, letting you take a reading of the mass in Newtons.

The wind of a tornado may be remotely measured using Doppler radar. In rare instances an anemometer makes it inside a tornado and measure wind directly. However, most tornadoes never have their winds actually measured. Instead the wind speed is estimated from the severity of the damage using the parameters of the Enhanced Fujita scale.
Effort is when you apply force on a tool to make it work(mostly in mechenical cases).

The push or pull exerted on one object by another is simply a force and this is measured in Newtons. Using Newtons second law: Force = mass * acceleration, we can see that one Newton is the force required to move a one kilogram mass at a rate of one meter per second squared.

Depending on the size of the rock - if it is small enough it can be measured in a container with water the size can be judged by seeing how much water it displaces

Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
