Unformatted text preview: is. A Rigid Body does not change shape when a load is applied A Concentrated Force represents the effect of a loading that can be assumed to act at a point on the body. Weight is a measure of the force of attraction between a body and the earth. It is not an absolute quantity and varies with location. W = mg. 1.3 Units of Measurement SI Units – The International System of Units is a mass ­based system. Therefore the mass of an object is normally given. If the weight of the object is required, the mass must be multiplied by gravity (9.81 m/s2). • • • • length – meters, m time – second, s mass – kilograms, kg force – Newton, kgm/s2 US Customary Units – This system of units is a force ­based system. Therefore objects are represented in terms of weight and no adjustment is required. • length – feet, ft • time – second, s • mass – slug, lbs2/ft • force – pound, lb 1.5 Numerical Calculations In statics we will generally round off the answers to three significant figures since most of the data in engineering mechanics is reliable to this accuracy....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
