(b) Assume that the two loads acting on the truss above have been removed and the members
AB and BC experience a temperature increase of 60°C. Determine the vertical
displacement of joint C for this thermal loading. Take coefficient of thermal expansion of
both AB and BC as 12x10-6 / °C.
(c) If the truss is acted upon by the two loads and the temperature increase, determine the
vertical displacement at joint C.
