However simple this may seem, it is important to keep your unit systems straight and the differences between mass and force. (a) What are the two mail unit systems in material biomechanics to be aware of? (b) What is a kip? (c) What is a ksi? (d) What arc the units of weight in each of the two main unit systems? (e) What are the units of mass in each of the two main unit systems? (f) Is weight a measure of mass or force? (g) How are weight and mass related it the two unit systems?

Solution

(a) Metric System and Imperial System

(b) A kip is an imperial unit of force. It equals 1000 pound force. It is used as a measurement of loads.

(c) A ksi is a scaled unit of pressure. One ksi is equal to 1000 psi (pounds per square inch)

(d) Metric Sytem- Newton, kiloNewton

Imperial system- pound force, slug

(e) Metric Sytem- gram, decagram, hectogram , kilogram , Myriagram , Quintal, Ton

Imperial system- ounce, pound and stone

(f) Weight is a measure of force
