A simply supported Warren truss of 10 m span carries a uniformly distributed load (UDL) of 10 kN/m over its entire top chord. What are the vertical reactions at the left and right supports, respectively?

A column is subjected to Euler's crippling load Ph of flexural rigidity EI having both ends of the column hinged. If the same length of column is fixed at one end and free at the other end, and subjected to Euler's crippling load Pf with flexural rigidity 4EI, what is the relation between the two critical loads Ph and Pf?

A fixed beam of span 4 m carries a central point load of 40 kN. Calculate the magnitude of the fixed end moments.
