I want to be a member of this forum for the prime reason to learn about other aspects of physics that currently I am unaware of.

I am not a mathematician but an Engineer-in-Training studying mechanics. That being said why does equation I-10 equal 1 when k equals i and 0 when k does not equal i?

1 watt equals 1 Newton metre 1 kg equals 9.81 Newton metres 2.5 kg = 24.525 Nm = 24.525 Watts of mechanical energy.

I would love to find a materials book that is comparable to Taylor's Classical Mechanics. Taylor's book is well written with good problem sets, and it's designed for undergraduates. I also like that it burrows into one subject for 300 pages instead of being a general textbook with 2000 pages.
