However, it seems to me that the ideal scenario, in which it would fail at the highest possible load, the total load would be distributed in proportion to their compressive strengths if one 2X4 was three times as strong for example, it would take three times the load. I don't really understand the second point though (assuming that the two 2X4s would buckle as a single beam) because the 4X4 and the two 2X4s would both have the 4in by 4in dimensions.Īnother reason given is that there would be variation between the mechanical properties of the two pieces of wood one 2X4 would have a greater compressive strength for example. I think on a similar point, the grains between the two blocks wouldn't be aligned so would failure along grains potentially be blocked along the boundary? I think the first point makes good sense to me. The reality is much more complex, but does not change the overall conclusions. The thin direction is twice as thick in doubled 2 X 4's, so has eight times the resistance to buckling.Ĭaveat: The above is simplified. With doubled 2 X 4's, the knots do not line up, so the assembly is stronger.Ģ) If it's used as a long column, the maximum load is limited by buckling in the thin direction. We believe that businesses have an obligation to solve the climate crisis and Cura Terrae will help them meet and maintain environmental standards across land, air and water.1) Real world 2 X 4's have knots in them. He said : “Our mission at Cura Terrae is to take care of the earth. In a fragmented marketplace for environmental services, CEO Prof Peter Skipworth sees a significant opportunity to build a leading nationwide consultancy. Palatine Impact Partner James Gregson, who led the investment with investment manager Greg Holmes, will also be joining the board. Piers Clark, the respected water sector professional, will become non-executive Chair of Cura Terrae and will also remain as executive chair of Isle Utilities, the specialist water consultancy. Pete Skipworth will become Cura Terrae’s Group CEO and Sara Blannin will be Group CFO. With the momentum we have generated and the financial backing from Palatine we are well placed to increase our market share in 2022.” I would like to say a huge thank you to the entire Envirocare team for rising so selflessly to every challenge they have faced this is not something I take for granted. Being part of Cura Terrae will allow us to deliver a wider range of environmental services at a time when this has never been more important. “The formation of Cura Terrae presents a wonderful opportunity for Envirocare to work alongside ECUS and EMS, creating a strong group of passionate, knowledgeable individuals. John Healey, MD of Envirocare is looking forward to the formation of the group, he says: Established in 2002, it has grown its staff count from seven to 90.Įnvirocare will maintain its area of expertise but will benefit from the consolidation of shared central services such as marketing, HR and finance, who will relocate to the Brook Holt offices in Sheffield. Ecus bring 154 members of staff to the wider group, including their recent acquisition, Northern Archaeological Associates.ĮMS specialises in water and air quality testing for the utility sector to ensure its industrial clients standards are aligned with government regulations. Services include air quality, arboriculture, carbon services, ecology, environmental services, habitats, heritage & archaeology, landscape architecture, and water services. Headquartered in Sheffield, Cura Terrae, which means ‘take care of the earth’ in Latin, is a purpose-driven business led by experienced entrepreneur, and current MD of EMS, Professor Pete Skipworth, who will look for suitable complementary acquisitions as part of a strategic growth plan.Įnvirocare will be moving out of the EMS group and will instead sit alongside EMS and Ecus under the new group of Cura Terrae.Įcus provides holistic environmental consultancy services to support the development of UK infrastructure. We are delighted to announce that Envirocare is now part of Cura Terrae a newly created environmental service group, which will also include Ecus and Environmental Monitoring Solutions (EMS).
