AI Thread Summary
The discussion revolves around optimizing shear stress in structural analysis through the application of force and momentum equilibrium. The first case can be solved to determine forces F_a and F_b, but the second case lacks sufficient information for a complete analysis. It is noted that removing visible forces could still result in shear on the bolt due to tensions and compressions in adjacent members. An approach suggested involves treating one of the left-side forces as an unknown to express shear values in relation to it. The conversation emphasizes the need for more details to effectively analyze case b.

What are the sums of the forces for each case?

I just can solve problem ##a## by apply equilibrium of force and momentum to find ##F_a## and ##F_b##. But with case b, I can't find third equation.osilmag said:

Yes, b) is not fully specified. E.g. you could take away all of the shown forces and still have shear on the bolt resulting from tensions and compressions in the members on the left.alexteplyaxins said:
You could set one of those on the left as an unknown and find the shears in terms of that, then find the value of the unknown which minimises the maximum shear.
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
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
$$T + f_f - N_w = Ma$$
