1. Pressure is defined as force per unit area that a fluid exerts on its surroundings. You can measure this force by detecting the amount of deflection on a diaphragm positioned inline with the fluid. Given the known area of the diaphragm, pressure can then be calculated. Pressure sensors are packaged with a scale that provides a method to convert to engineering units.
The padded feet of a Bengal tiger that enables it to silently stalk prey. 1  The claws of the tiger are up to 10 centimeters (4 in) in length and are used to grasp and hold onto prey. Each paw has four of these claws and one specialized claw called a dewclaw.
