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...
Vernier Calipers Vernier Calipers are measuring instruments which can measure mainly diameter of the circular objects. They can take smallest reading up to 0.01cm which is known as its Least Count. They are of two types: Analog Vernier Calipers Digital Vernier calipers Below Figure (i) Shows Analog Vernier Caliper while figure (ii) shows Digital Vernier Calipers. Figure (i): Analog Vernier Caliper Figure(ii): Digital Vernier Calipers In this lecture we will be focusing on Analog Vernier Calipers . CONSTRUCTION OF VERNIER CALIPERS: From Above figure will will describe each of its Component separately: It consisted on two scales (i) Main Scale and (ii)Vernier Scale. Main Scale (MS): Main Scale of the Vernier Scale contains the division and each division on the main scale is of 1mm. M...
