This is desperation but are there any engineers or mathematitians who understand Virtual Work on an Inderterminmate Beam that fancy helping me solve a question?
I feel cheecky for posting this but hey what the hell lol  |

yeah,all you have to do is Using equation (1), solve for YB:
-63200 (k-ft3)/EI + 2666.67 (k-ft3)/EI * YB = 0
YB = 23.7
Multiply the unit load, Q, at YB by 23.7 to get the final reaction. The positive answer indicates that the reaction is in the direction of the applied unit force.

"yeah but to truely learn you must do it yourself so for your own good i am not going to help you  "
pmsl cheers for that lol remember you said that when they find me delerious and banding my head on the wall lol |

Simply write first the compatibility equation, and find the deflections on the primary structure by using virtual work and find the flexibility coefficients by virtual work, too.  |

Do you mean deflections ? If you do .....
Simply write first the compatibility equation, and find the deflections on the primary structure by using virtual work and find the flexibility coefficients by virtual work, too.
For your case there is 1 compatibility equation of the form (considering deflections down positive):

"Not sure, r u talking
- II theorem of Castillan
- Maxwell-Mors integrals
- Theorem of Vershchagin
here? "
can't be verschagin's because then you would have to include Logical operations and Kolmogorov complexities into the minimum length programs to translate between given strings |

" Granny.
Google is indeed your friend, especially if you use spell checker too. "
Laine. I did not use Google .... ffs ..... I worked it all out in my head.... I think he may have been talking about
Separate moment equations required for different regions of beam.
e.g.
After integrating equations separately to get slope and deflection equations, extra constants of
integration found by equating deflections and slopes at points where 2 equations apply, e.g. at
B.
integrating 2 equations twice gives 4 constants of integration
2 found by using v= 0 at A and C
2 found by equating slope and deflections at B.
Method becomes very complicated if more points loads - other simpler methods available
This tho really .........  |

Can anyone tell me the force required to hold a 10 tonne load, which is on steel wheels, on rails, on an incline of 29 degrees?
Also, is elastic stretch of steel wire proportional to load applied?
Serious questions  |

Force will be load * sin theta
So 10 tonne * 9.81 (Gravity) * sin29
ie.
10*10^3 * 9.81 * sin29
= 47559 kN
I think
Also
strench is due to strain and strain is proportional to stress, stress as iduced by the load.
So yes....its youngs modulus |
