Challenge Problems
Push your limits with challenges.
Question 1
Assume a truss composed of two members forming a right triangle, with lengths of 3m and 4m, and a vertical load of 10,000N at the junction. Calculate the internal force in each member using the principles of truss analysis.
💡 Hint: Draw a free-body diagram to visualize the forces acting on the truss.
Question 2
A truss member of length 6 m with a cross-sectional area of 0.02 m² and modulus of elasticity 210 GPa is subjected to a tensile load of 50 kN. Calculate the elongation of the member.
💡 Hint: Pay attention to make sure all units are consistent when substituting into the formula.
