- 2. INTRODUCTION Why are we going to discuss about this concept?? As a mechanical and civil engineer, we always work with machines under Structural loads or we will be going to design construction with different types of supports and beams. This is a basic concept for an engineer to be aware of to do all such things. By the end of this concept we are expecting a student will be capable to identify all the supports, beans and loads.
- 3. Types of Loads •Point Load •Uniformly Distributed Load •Uniformly Varying Load
- 4. Point Load • When a load acts concentrated at a definite point then it is named as a concentrated load or point load. We can see some best examples of point load in the below figures.
- 5. UNIFORMLY DISTRIBUTED LOAD • A distributed load is a load which is spread on some length of a beam, i.e. The reason it is measured in intensity with units Newton/Meter. • If the intensity is constant along the length then it is named as UDL.
- 6. UNIFORMLY VARYING LOAD • A distributed load is a load which is spread on some length of a beam, i.e. The reason it is measured in intensity with units Newton/Meter. • If the intensity is constant along the length then it is named as UDL.
- 7. Types of Beams •Fixed Beam •Cantilever Beams •Beam with one end hinged and the other end roller •Simply Supported Beams •Over Hanging Beams •Continuous Beam
- 8. Fixed Beam • A Beam which is having fixed supports on the both of its ends, it is named as fixed beams and we can see some animated and real examples of these kind of beams and how they restricting the movement of the beam.
- 9. CANTILEVER BEAM •A Beam which having a fixed support on end other end is set free, it is known as cantilever beam
- 10. BEAM WITH ONE END HINGED & OTHER END ROLLER •This beam has one of its end hinged and the other side of the is supported with roller. •These kind of beams are capable to withstand loads in any direction.
- 11. SIMPLY SUPPORTED BEAM •A beam with simple support exactly at two ends of the beam then is called as simply supported beam.
- 12. OVER HANGING BEAM • THESE BEAM WILL ALSO HAVE SUPPORTS BUT ONE END OR BOTH END OF THE BEAM WILL HAVING SOME EXTENSION AFTER THE SUPPORT
- 13. CONTINUOUS BEAM •It is beam which carries more then two support.
- 14. TYPES OF SUPPORTS •FIXED SUPPORT •SIMPLE SUPPORT •ROLLER SUPPORT •HINGED SUPPORT
- 15. FIXED SUPPORT •This support keeps the end of the beam fixed, i.e. The beam end resists to take any kind of translation or bending moment.
- 16. SIMPLE SUPPORT •In this type of support, the beam is allowed to rest freely on a support.
- 17. ROLLER SUPPORT •A roller support gives capability of movement to the respected beam connected to it may be along normal guides or it can also rotate about the support.
- 18. HINGED SUPPORT • A hinged support restricts the movement of the beam in any direction but it will allow the beam to rotate about the support just like a door.
- 19. SUPPORT REACTION CALCULATION To explain support reaction calculation • We took an example, • Find the reaction at the support of the following beam.
- 20. Solution, ∑Mc =0 Clockwise moments = Anti clock wise moments R1 x 6 = 1000×3 + (200×3)3/2 = 3600 6R1 = 3000 + 900 = 3900 R1 = 3900/6 = 650 kg. R1 = 650 kg
- 21. For calculating R2 i.e. reaction at point C, Total vertical force=∑FV =0 R1 + R2 = 600 + 200×4 1300 + R2 = 1400 R2 = 1400 + 1300 R2 = 100 kg Therefore, R1=650kg R2=100kg
