Hi
I have some questions to go through for static equilibrium...I have the answers but I have no idea how to do these really - I am guessing most of them without really understanding
I can't remember doing physics in shcool at all and since its been the best part of 20 years since school some help would be REALLY appreciated
Ok ill put two sample questions with the answers that were also given
A horizontal beam AB is simply supported at each end. The beam carries a point load of 12kN at a point 0.8 m from A, a point load of 8kN at a point 1.9m from A and a point load of 15kN at a point 3m from A. Calculate the reactions exerted by the supports on the beam.
The answers are : 17.55kB at A and 17.45kN at B
Another one
A horizontal beam AB is 6m long and simply supported at each end. The beam carries a uniformly distributed load of 3kN/m from each end A to the mid point of the beam, a point load of 9kN at a point 2.1m from A, and a point load of 14kN at a point 4.7m from A. Calculate the reactions exerted by the supports on the beam.
(answers are 15.63kN at A and 16.37kN at B)
If anybody can find the time to really explain how these are generally worked it out would be great
Ive already ordered books from amazon to hopefully help me out as this is beyond me at the moment - even google is failing me!
Thanks
