I want to make some TextBox es on my form uneditable, but I want the text to be clear (black not gray) and that's why I do not want to use. myTextBox.Enabled = false; Somehow I want it to be disabled but with non-gray fore-color.
Simple machines are devices that can make a tough job easier by enabling a person to apply less force or to apply force in a direction that is easier to manipulate. There are six types of simple machines: lever, pulley, inclined plane, wedge, screw, and wheel and axle. Each machine affects the direction or the amount of effort needed to do work. Most mechanical machines, such as automobiles or power tools, are made up of hundreds of parts. However, no matter how complex a machine is, it is composed of some combination of these six simple machines.

Students are introduced to three of the six simple machines used by many engineers: lever, pulley, and wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines helps determine their ability to make work easier or make work faster.
