Which of the following statement is true for following statements about universal measuring instrument? Statement 1: Microprocessor and micro switches are present. Statement 2: Coefficient of thermal expansion of measuring instrument made of steel is the same as a component to be measured.

Correct Answer: T, T
Same coefficient of thermal expansion of measuring instrument and component to be measured hence, there is no effect of temperature variation on measuring accuracy.

To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met?
1. Each end of the trunk link must be set to the IEEE 802.1e encapsulation.
2. The VTP management domain name of both switches must be set the same.
3. All ports on both the switches must be set as access ports.
4. One of the two switches must be configured as a VTP server.
5. A rollover cable is required to connect the two switches together.
6. A router must be used to forward VTP traffic between VLANs.

In the question two statements are given, followed by two conclusions, I and II. You have to consider the statements to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement I: Some buttons are switches Statement II: All buttons are connectors Conclusion I: Some switches are connectors Conclusion II: Some connectors are buttons

Which of the following statements are true?
1. The coefficient of rank correlation has the same limits as the Karl Pearson's coefficient of correlation.
2. The coefficient of correlation is independent of the change of origin but not of scale.
3. The covariance between $$X$$ and $$Y$$ is defined as $$\frac{{\sum {xy} }}{n}$$ where, $$x = \left( {X - \overline X } \right),y = \left( {Y - \overline Y } \right)$$      and $$n = $$ no. of paired observations.
4. $${b_{xy}}$$ is called regression coefficient of $$X$$ variable on $$Y$$ variable.
5. If $${b_{xy}}$$ is 0.4 and $${b_{yx}}$$ is 1.6, coefficient of determination would be 0.8.

What is the relation between the Coefficient of thermal expansion of concrete and the coefficient of thermal expansion in aggregates?

From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.

Coefficient of thermal expansion of concrete is __________ coefficient of thermal expansion in aggregates.

Coefficient of thermal expansion of concrete is ________ coefficient of thermal expansion in aggregates.

The coefficient of thermal expansion of concrete is similar to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.

The coefficient of thermal expansion of concrete is very small to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.

Which of the following option is true for the given statements? Statement 1: Stainless steel has a high thermal coefficient of expansion than cast iron hence used to make scales. Statement 2: Most of the scales are produced by duplicating from master scale.
