When considering a limit of d when L is a value, should we assume that by limit of d, it means that the absolute highest and lowest d can be when point A moves on its rod? Being a statics problem, we just arent sure if this is a safe assumption. Show your work & explain the limits on d physically as it relates to the system.Īnother student from this class and I worked at it for an couple hours and it just isnt clear what we can and can't assume about the geometry of this system. The length of the bar is 1.5m.ī.ğor L = 0.5 m, what is the limit for d?Ĭ. The center of mass of the bar is at its midpoint. The problem I have pasted into this post gives d a limit at (0.5 ≤ d ≤ 1.5 cm), but I do not know how that limit is logical.Įnds A and B of the 5-kg rigid bar are attached by lightweight collars that slide over the smooth fixed rods as shown in the figure. Looking at the figure, I really don't seem to have enough information to say what an acceptable limit of d would be. In another version of this problem that my class is supposed to do, we have to figure out the 'limit' of d in terms of L which is 1 meter in this problem setup. Point B only has resisting forces in i and j directions Point A only has resisting forces in i and k directions Determine the horizontal force F applied toĬollar A that will result in static equilibrium as a function of the distance, d (0.5 ≤ d ≤ 1.5 cm). Ends A and B of the 5-kg rigid bar are attached by lightweight collars that may slide over the smooth fixed rods shown in the figure.
