FARM STRUCTURES CONTINOUS ASSESSMENT TEST LATEST UPDATE

1. What is the function of roller supports? ANSWER-are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. 2. What is the function of frictionless surface supports? ANSWER-are similar to roller supports. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. 3. What is the function of pinned support? ANSWER-can resist both vertical and horizontal forces but not a moment. They will allow the structural member to rotate, but not to translate in any direction 4. What is the function of fixed supports? ANSWER-can resist vertical and horizontal forces as well as a moment. 5. What is Dead Load (DL)? ANSWER-loads that are assumed to act permanently and stationary. They are usually expressed in kPa or kN/m3
