Physical Principles of Design Lecture-1 Monday 13.January.2003 Basic Physical Principles
Basic Physical Principles • Motion and Acceleration • Static Equilibrium • Properties of Fluids • Temperature and Heat • Strength of Materials and Elasticity • Electromagnetic Properties and Light • Optics and Images
The SI System of Units a.k.a. “The Metric System” a.k.a. MKSA M for meter, K for kilogram;S for second, A for ampere. Other units(e.g. Joule,Newton) are derived from these. “Always stick with SI units and everything will come out ok.”
Specific Units Length: meter(m); Time: second(s); Mass: kilogram(kg). Length(m); speed(m/s); acceleration (m/s2) units: Kg m/s2=Newton(N) Energy: N m=Joule=Kg m2/s2=J Power: energy/time=J/s
