subject name: design of timber structures

In a roofing system for a restaurant in Melbourne, member AB is part of a truss and is subjected to a factored compression force of 20kN. This force comes from load combination of permanent load and medium-term (5 days) live load. This member is made of 140mmx5mm unseasoned F22 timber. The length of member is 3.5m. Member AB is restrained at both ends in position only. Considering only the major axis, check the capacity of member AB to resist the compression force.
