The limits of a shaft designated as $$100h5$$ are $$100.000$$ $$mm$$ and $$100.014$$ $$mm.$$ Similarly, the limits of a shaft designated as $$100h8$$ are $$100.000$$ $$mm$$ and $$100.055$$ $$mm.$$ If a shaft is designated as $$100h6,$$ the fundamental deviation (in $$\mu m$$ ) for the same is

The roughness profile of a surface is depicted below.

The surface roughness parameter $${R_a}\,\,$$ (in $$\mu m$$) is ________________.

A beam is subjected to an inclined concentrated load as shown in the figure below. Neglect the weight of the beam.

The correct Free Body Diagram of the beam is

Consider the following statements:
(P) Hardness is the resistance of a material to indentation.
(Q) Elastic modulus is a measure of ductility.
(R) Deflection depends on stiffness.
(S) The total area under the stress-strain curve is a measure of resilience.

Among the above statements, the correct ones are
