Will this configuration reduce the shear stress on the main beam?

AI Thread Summary
The proposed configuration of two small beams in a V shape beneath a main beam aims to reduce shear stress by distributing the load more effectively. The interaction between the small beams creates a "press fit," which exerts both shear and compressive forces, potentially alleviating stress on the main beam. There is a consensus that this setup should indeed lower shear stress, as it enhances support and load distribution. No significant reasons have been identified that would counter the effectiveness of this configuration. Overall, the design appears beneficial for reducing shear stress on the main beam.

Imagine a moderately long beam fixed at one end to a wall. Near the end of the beam, a very heavy weight is kept on top of the beam. At the same spot, two small beams are fixed under the main beam in a V shaped configuration such that the two beams form a sort of "press fit" i.e. they exert a substantial shear and compressive force on each other and on the main beam.

Will this configuration reduce the shear stress on the main beam?

Let me ask: is there any reason to think this configuration would not reduce the shear stress on the main beam?
 
I can think of none
 
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...
