WebLC=1 MSD – 1 VSD. When the vernier scale has n divisions and it coincides with the the main scale at (n-1) division, the vernier calliper with the least count is: LC= (1-n-1/n) ×MSD. The least count of vernier calliper is 0.1 mm. In the above … WebScrews: One can consider a screw and a bolt as a combination of two wedges. One wedge is obtained from opening the helical treads of the screw and the other will come from opening the helical threads of the bolt.

Webmass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force. The unit of mass in the International System of Units (SI) is the … WebSee How a Screw Works. An inclined plane, such as a ramp, is a kind of simple machine that helps do work. A screw, just like the ones from a hardware store, is also a simple machine! A screw is made from an inclined plane being wrapped around and around. To see how this works, you will need notebook paper, and a pencil or marker. 1.
WebThe concept of rotational equilibrium is an equivalent to Newton’s 1ˢᵗ law for a rotational system. An object which is not rotating remains not rotating unless acted on by an external torque. Similarly, an object rotating at … WebThe pitch of the screw is equal to the distance travelled by the screw on the pitch scale divided by the number of rotations made by the head scale. Least count ( L.C) = Pitch of the screw / Number of head scale divisions Description of a Screw gauge Screw gauge consists of a U shaped metallic frame(F). To one end of the frame, a stud S 1 is ...
WebCap and machine screws are used to clamp machine parts together, either when one of the parts has a threaded hole or in conjunction with a nut. These screws stretch when tightened, and the tensile load created clamps the parts together. The setscrew fits into a threaded hole in one member; when tightened, the cup-shaped point is pressed into a mating … WebFollowing are the two factors on which friction depends: 1. On the nature of the two surfaces that are in contact Friction is dependent on the smoothness or roughness of the two surfaces that are in contact with each other. When the surface is smooth, the friction between the two reduces as there is not much interlocking of irregularities.
