A uniform beam of length 6 m has a weight of 180 kN and is supported at its ends. If it carries a uniformly distributed load of 60 kN/m over a length of 3 m from the left-hand end to the mid-span point, what are the reactions at the supports?

A pipe has an external diameter of 35 mm and an internal diameter of 30 mm. What is the tensile stress acting on the pipe if it is subject to a tensile axial load of 800 N?
