Difference between Mechanical Comparator and Electrical comparator

Metrology Engineering, Uncategorized / By /

The difference between mechanical Comparator and electrical Comparator is as follows: MECHANICAL COMPARATOR: The Mechanical Comparator has more number of moving parts.  Due to more moving parts present in this system there is a high rate of wear and friction. Mechanical comparator is not high accuracy. Readings of this Comparator do not affect by variations …

About reinforcements

Metallurgy, Uncategorized / By /

Explain about the Uses of Reinforcements: Different types of reinforcements are used to increase the mechanical properties of metals by adding it. In this Continuous reinforcement is more effective than discontinuous reinforcement, flakes, particles etc. Continuous is more effective due to the equal distribution of load to the entire structure. There is a high strength …
