1. A screw gauge consists of U- shaped metallic frame F. To one end of this frame, a flat shaft is fixed. On the opposite end of a hollow long cylinder C is fixed.2. The hollow cylinder has fine threads cut inside it and it serves as the nut.On the outer surface of this hollow cylinder, a line parallel to its axis, called index line is drawn and is divided into some equal divisions (1 mm or 0.5 mm). This serves as the pitch scale (P).3. A screw with a flat tip (shaft) having threads exactly identical to the threads cut inside the cylinder, moves through the cylinder C. To the other end of the screw, a milled head M is connected.4. To this milled head one end of a barrel B (another hollow cylinder) is connected. This Barrel B forms a jacket to the first hollow cylinder C.5. The other end of the barrel is tapered and has 100 or 50 equal divisions on it. This is called the head scale (H).6. When the two flat shafts exactly opposite to each other , are in contact, the distance between them is zero. In this position, the edge of the head scale must coincide with the zeroth division of the pitch scale.Further, the index line will be coinciding with the zero of the head scale
what are advantages and disadvantages for the six''s thermometer
Harmonicmotion is considered simple if it is undamped, i.e. if it keep on to oscillate uniformly over time. Of particular interest are the frequency f or also period T of the oscil
1. Cell growth. if V is the volume of a spherical cell, then, in certain cell growth or for some fetal growth models, the rate of change of V is given by dV/dt =kV2/3, where k
Refractive index: The most important optical measurement for any transparent material is its refractive index (n). The refractive index is the ratio of the speed of light (c)
A 1.25-kg box is being pulled across a level surface where μk is 0.80. If the string is suddenly cut, causing the applied force to immediately go to 0.0 N, what is the rate of
The light passing through a quarter wave plate is analysed by a rotating Nicol prism. It is get that the intensity of the emergent light beam from the rotating Nicol prism becomes
The first question one might ask about ferromagnetic material is the source of the large magnetism. The saturation magnetization is so large virtually all the magnetic dipoles in t
Ball A, with a mass of 0.20 kg, strikes ball B, with a mass of 0.30 kg. The initial velocity of ball A is 0.95 m/s. Ball B is initially at rest. What are the final speed an
Friction is a microscopic constant and so macroscopic level area does not matter. But area would matter if the object we''re putting under study was microscopic, which isn''t in o
