AN ABSTRACT OF THE THESIS OF Joel Hartter for the degree of Master of Science in Forest Engineering presented on April 21, 2004. Title: Investigation of Synthetic Rope End Connections and Terminations in Timber Harvesting Applications Abstract approved: John J. Garland Steel wire rope is the accepted standard in logging. It is strong, durable, stiff, and dependable in the logger’s arsenal. However, steel wire rope has several disadvantages: its strength to weight ratio is low; it is difficult and time-consuming to splice; and used wire ropes contain jaggers. Ultra-high molecular weight polyethylene (UHMW-PE) braided rope has potential to replace steel wire rope. The offshore mooring and shipping industries have appreciated it for years. Characteristics such as a specific gravity less than one (it floats!), high flexibility, low stretch, and ease of splicing make the synthetic rope useful. At equivalent diameters, synthetic rope has an equal or greater breaking strength to that of steel wire rope, but at 1/7 the weight. This thesis is an investigation of the end connectors for the unique physical, mechanical, and thermal properties of UHMW-PE 12-strand braided rope that make this technology of interest in logging applications. This studied focused on three diameter classes of the synthetic rope that are common to logging operations: 3/8”, 9/16”, and 5/8”. Within each diameter class there were five different spools representing separate production runs. A randomized complete block design was used with each diameter class and the corresponding five spools a separate population. Following the laboratory tests, the breaking strengths were compared to the buried eye splice. Three types of end connectors were evaluated during this pilot study. They are identified as spliced, adhesives, and dry hardware. Spliced end connections provided consistent performance in breaking strengths. The end connections with adhesives had variable strength performance laboratory tests and are therefore not recommended. Within the dry hardware end connections, the pinned nubbin and knuckle link provided the highest breaking strength relative to the buried eye splice. This project has accomplished its objectives. It was the first extensive study on end connections specifically designed for synthetic rope. New end connections were developed and steel wire rope connections were modified to meet the strength and usability criteria for timber harvesting operations. Suitable end connections for forest operations were: buried eye splice, Whoopie Sling, long splice, rope clamps, knuckle link, pinned nubbin, and Y-splice. These end connections suitable for use with forest operations were identified and recommended user guidelines were given. Further research and development needs to be conducted on these seven concepts with larger sample sizes and in varied conditions. ©Copyright by Joel Hartter April 21, 2004 All Rights Reserved Investigation of Synthetic Rope End Connections and Terminations in Timber Harvesting Applications by Joel N.

    Portable Hammock Stand Design and Business Model Development

    PORTABLE HAMMOCK STAND DESIGN AND BUSINESS MODEL DEVELOPMENT Evan Keith Industrial Technology Orfalea College of Business California Polytechnic State University March 14th, 2013 ABSTRACT Currently hammocks are thought of as stationary relaxation devices that use tress as support structures. The industry mainly focuses on hammock innovation over the way in which the hammock is actually hung. Having been around for thousands of years, reinventing the idea of the hammock is not something that is occurring or has been thought of. This senior project proposes the idea of a portable or more adaptable hammock stand. It takes the idea of hammocks as stationary devices to them being something that can be taken almost anywhere. Shifting how hammocks are thought of and exposing the potential they posses by introducing an innovative hammock stand. The report discusses the design and use of a light weight easy to use hammock stand. Through market research and product development, a portable hammock stand is presented with a rough business plan as to how to make a sustainable business model around the product. ii ACKNOWLEDGMENTS iii TABLE OF CONTENTS Abstract…………………………………………………………………………………………ii Acknowledgments ……………………………………………………………………………..iii List of Tables……………………………………………………………………………………v List of Figures…………………………………………………………………………………...v Section Page I…………………………………………………………………………………………1 II………………………………………………………………………………………...7 III……………………………………………………………………………………….17 IV……………………………………………………………………………………….32 V………………………………………………………………………………………...37

    2006 Annual Bibliography College of Forestry and the Oregon Forest Research Laboratory From the Director Contents regon has a strong reputation as a global leader in forestry and forest products, and it Ocontinues to be the nation’s leader in softwood lumber production. In addition to providing sustainable, economic benefi ts to Oregonians, the forestlands promote environmental and water quality, provide fi sh and wildlife habitats, meet social and recreational needs for the people, and are vital to climate moderation. Providing the research and management expertise to optimize the multiple, and sometimes competing, values of our forests and enhance the effectiveness of forest sector industries is the task of the Oregon Forest Research Laboratory. Our scientists collaborate with peers in other organizations and other disciplines to discover ‘new’ knowledge, as well as to challenge or expand on current knowledge related to the processes, interactions, and impacts of forestry, natural resources, and ecosystem activities. The knowledge generated from these efforts is routinely made available via a broad range of publications. This annotated bibliography is intended to recap the scientifi c fi ndings published between January 1 and December 30, 2006. The information is arranged in fi ve program areas, but I believe you’ll fi nd the richness and depth of the research being conducted by our scientists goes well beyond these thematic terms. This booklet is a strong testament to their productivity, and to the state, federal and private organizations that help fund our continuing quest for the knowledge that will help the natural resources, ecosystems, and citizens of Oregon, the nation, and the world.
