Exercise 1. Let P is a set of integer multiple of 3. Show that by using addition and multiplication operation on set P forms a commutative ring. Integral Domain Definition: A commutative ring which does not have zero divisors is called as Integral Domain. Example: 1. Is it an Integral Domain? So, determine whether f is a bijective homomorphism isomorphism.

With the samples of set above, we can define the structure of ring as follows: Definition. Set S is considered as subring of R if S is also Ring toward the same addition and multiplication operation in Ring R.

So that we can drag a conclusion, that: Subring is a Ring inside a Ring. Two Other Samples of Subring 1. However, tension rings are provided with threaded bosses and supplied with pulling rods which are screwed onto the bosses. The proving ring consists of two main elements, the ring itself and the diameter-measuring system, shown on the right in the exploded view of a proving ring. Forces are applied to the ring through the external bosses.

The resulting change in diameter, referred to as the deflection of the ring, is measured with a micrometer screw and the vibrating reed mounted diametrically within the ring. The micrometer screw and the vibrating reed are attached to the internal bosses of the ring.

In modern rings, the upper and lower internal and external bosses are machined as an integral part of the ring to avoid mechanical interferences during the application of the force.

To read the diameter of the ring, the vibrating reed is set in motion by gently tapping it with a pencil. As the reed is vibrating, the micrometer screw on the spindle is adjusted until the usa-button on the spindle just contacts the vibrating reed, dampening out its vibrations. When this occurs a characteristic buzzing sound is produced.

At this point a reading of the micrometer dial indicates the diameter of the ring. The number of divisions on the micrometer dial and the graduation of the vernier index vary by type of proving ring.

Typically, proving rings are designed to have a deflection of about 0. The relative measurement uncertainty can vary from 0. How did the proving ring come about? Why measure force? Calibration of the proving ring.
