Distributed load - model bridge project

AI Thread Summary
In a bridge project, a 20kg load applied to the center of a loading plate raises questions about load distribution among the side beams. The discussion clarifies that if the load is a point load, each long side beam would indeed support 10kg, equating to 98N each, assuming the load is evenly distributed. The participant seeks to simplify the loading plate for calculations related to moments and shear forces. The focus is on determining the tension in the cables supporting the structure. Overall, the conversation emphasizes understanding load distribution for accurate structural analysis.

so this is for a bridge project right and that picture is simply a basic design just enough to get the jist to answer my question.

what I am wondering is, if 20kg's was applied to the very centre of that loading plate - is it fair to say that each of the long side beams are supporting 10kg's each? or am i looking at this all wrong

also, 20kg's = 196 Newtons, but in this case - is it 196N/m, or just a evenly distributed load of 196N hence each long side beam supporting 98N

all I am after is just looking for a way to simplify the loading plate so i can find out moments and shears etc, stuff like that

Homework Equations


The Attempt at a Solution



at the moment I've simplified the load to a point load in the middle of the loading plate, just trying to clear up my confusion

what i really need to find is the tension in the cables

thanks for any help

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
