20. A floor system in a small building consists of wood planks supported by 50 mm (nominal width) joists spaced at distance s, measured from center to center (see figure). The span length L of each joist is 3 m, the spacing s of the joists is 400 mm, and the allowable bending stress in the wood is 8 MPa. The uniform floor load is 6 La5 includes an allowance for the weight of the floor system itself. Calculate the required section modulus S for the joists, and then select a suitable joist size (surfaced Iumbes from Appendix F, assuming that each joist may be represented as a simple beam carrying a uniform load.

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
