Quest line has contacted the National Particleboard Association regarding your request. We spoke one of this organization's technical experts regarding the feasibility of using wheat straw in this manner. He stated that there is currently a plant in North Dakota that manufactures straw board and another plant under construction in Winnepeg, Canada. The wheat straw as a raw material is not necessarily as cheap as wood either and the manufacturer would have to compete against large wood particle board plants that currently exist. Dirt - The straw is not as clean as wood due to the inherent fashion in which the product is gathered.
Organization represents U.S. particleboard manufacturers.
Individual is looking for the formulas to analyze dynamic loading on a shaft. Quest line has found the formula to determine the diameter of a shaft given the torque, moment and loading parameters of the shaft. The text contains explanations of the variables involved along with the appropriate tables to determine the modification factors. Please take a look at this information and let us know if you need further assistance with applying it to your situation. In the meantime we will contact Ohio State University to see if a copy of a shaft design program can be purchased for future use.
