Thank you so much for your help SteamKing! :D I got it right :)

I have fixed my shear force equation and integrated it: ∫ - (950/13)x2 - 3490.096154x + 61837.91667 from x = 0 to x = 13.756 metres: BM = 61837.91667x - (3490.096154x2)/2 - [(950/13)]x3/3 so integrating from x=0 to x=13.756m: BM max = 457024.483 Nm

I just now realized that it isn't in equilibrium, thanks. Ignore my earlier comment. I looked back on my working and found the 950/13 comes from the weight of the triangular loading: W = 1/2(base)(height) = 1/2(x)(3800/26)(x) = 950/13(x^2)

This is the shear force equation: (I missed the '2' initially, I'm sorry for that!) v = (9250/13)x2 + 3490.096154x - 61837.9166 So through integrating from x = 0 to x = 13.756m I get that bending moment: MAX BM = 885754.75 Nm

Homework Statement Calculate the Maximum Bending Moment of the bridge section using the values given. Ra = 61837.91667 N Rb = 78304.5833 N (please refer to attached diagram) Homework Equations shear force is = 0 when x = 13.755998 m (I worked this distance and the shear force equation out...

Thanks! I did what you said and got it right :D

Homework Statement Calculate the maximum bending moment on the bridge section using the values given. (REFER TO DIAGRAM ATTACHED) mass of bridge = 9250 kg mass of car = 2250 kg length of bridge section = 26 m Homework Equations I worked out previously that: Reaction at A = reaction at B =...

Thanks for that PhanthomJay! :) My exam is very very soon and I'm glad you cleared that up for me.

I got it :) I realized that when taking the moment about C, the force Bx does not need to included. So Bx = -57 kN

Homework Statement For the frame shown (see attached picture) , work out the horizontal reaction at B (ie find Bx)Homework Equations EQUILIBRIUM EQUATIONS: sum of moment = 0 (CCW is positive) sum of vertical forces = 0 (up is positive) sum of horizontal forces...

Sorry and thanks for telling me! I've attached it on my reply Also, I don't know about the lagrangian formalism. :)

Homework Statement A pin is constrained to move in a circular slot of radius 39mm. At the same time a slotted bar also constrains the pin to move down with constant velocity 8mm/s. (as shown in attached diagram). What is the magnitude of the acceleration of the pin for the position...

Thank you!

ok thank you Cwatters and phanthomJay. I found it was possible to more than one force on one circle.
