Power

Power, in mechanics, is the product of force times distance divided by time; it measures
the performance of a given amount of work in a given time. It is the rate of doing work and
as such is expressed in foot-pounds per minute, foot-pounds per second, kilogram-meters
per second, etc. The metric SI unit is the watt, which is one joule per second.

Why first angle and third angle projection method is used in machine design and why second and fourth angle method is not used?

Image
In second angle, both top and front view are drawn above the x-line whereas in fourth angle its vice versa. In second and fourth angle method, top view and front view overlaps. hence we never use those methods. In first angle method, front view lies above the x-line and top view lies below. vice versa for third angle. As both the views lies on either side of x-line in first & third angle, we make use of these methods. (Abdul Karim)

surface roughness parameters:

Use the following formulas to convert average roughness (Ra) to other commonly used surface roughness parameters: R t = R a x 8.7 R z = R a x 7.2 R z ISO = R a x 7.6 R max = R a x 8.0 R p = R a x 3.6 RPM = R a x 2.9 RMS = R a x 1.1 The conversion formulas work regardless of whether R a is given in microinches (µin) or micrometers (µm). To convert metric R a to centerline average (CLA), use the following formula: CLA (µin) = R a (µm) x 40
