ThinkPad 700The IBM ThinkPad 700 (also named model 700 PS/2) is the first notebook computer for the ThinkPad brand that was released by IBM on October 5, 1992. Another series was released alongside it, the ThinkPad 300 series. The 300 series was meant to be a cheaper, lower performance model line over the 700. It was developed as a successor to the L40SX. The ThinkPad 700 is the first laptop model ever with a pointing stick to control the cursor, under the IBM brand name of TrackPoint.
Analog stickAn analog stick (analogue stick in British English), also known as a control stick, thumbstick or joystick, is an input method designed for video games that translates thumb movement into directional control. It consists of a protruding stick mounted on a pivot, with movement registered through continuous electrical signals rather than discrete switches, allowing for greater nuance than traditional digital inputs.
Computer mouseA computer mouse (plural mice; rarely mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was done by Douglas Engelbart in 1968 as part of The Mother of All Demos.
Computer keyboardA computer keyboard is a built-in or peripheralinput device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.
Cursor (user interface)In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input, such as a text cursor or a mouse pointer. EtymologyCursor is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy.
TouchpadA touchpad or trackpad is a type of pointing device. Its largest component is a tactile sensor: an electronic device with a flat surface that detects the position and motion of a user's fingers, and translates them into 2D motion to control a pointer in a graphical user interface. Touchpads are common on laptop computers, contrasted with desktop computers, with which mice are more prevalent. Trackpads are sometimes used with desktop setups where desk space is scarce.
TrackballA trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down ball mouse with an exposed protruding ball. Users roll the ball to position the on-screen pointer, using their thumb, fingers, or the palm of the hand, while using the fingertips to press the buttons.
ForceIn physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In mechanics, force makes ideas like pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity (force vector).

Different equivalent choices may be made for the expression of a strain field depending on whether it is defined with respect to the initial or the final configuration of the body and on whether the metric tensor or its dual is considered. Strain has dimension of a length ratio, with SI base units of meter per meter (m/m).*As an Amazon Associate I earn from qualifying purchases.
