HOOKE'S LAW Introduction In physics, Hooke's Law is one of the fundamental principles governing how objects deform under external forces . Named after the 17th-century British physicist Robert Hooke, this law provides a crucial understanding of the behavior of elastic materials, such as springs and rubber bands. Whether stretching a rubber band or compressing a spring, Hooke's Law helps explain what happens when forces act on these materials. What is Hooke's Law: Hooke's Law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. Mathematically, it is expressed as: F= -kx Here k represents the spring constant, which is the measure of the stiffness of the spring, and x is the displacement from the displacement position. The negative sign indicates that the force exerted by the spring is in the opposite direction of the displacement. Understanding the Spring Constant: The spring constant k is a critical co...
LOGIC GATES · Logic gates are the basic building block of the Digital System . · It is an Electronic circuit having one or more inputs, and only one output. · The relation between input and outputs is based on certain Logic. Based on this logic gates are named as AND gate, OR gate, Not gate. · Total there are Seven Gates, three are basic and other are derived from basic logic gates. ja 1. NOT Gate 2 2. AND Gate 3 3. OR Gate 4. NOR Gate 5. NAND Gate 6. XOR Gate 7. XNOR Gate 1. NOT GATE: NOT gate is also known as inverter. The symbols used for NOT gate are given as under, The Boolean expression for NOT gate is: X = A' Where X is output A' is the inverted version of the input A. When the inp...
