Item 4 A rigid, uniform, horizontal bar of mass m, and length L is supported by two identical massless strings (Figure 1)Both strings are vertical String A is attached at a distance d Note that critical as computed in the previous part, is not necessarily positive. If antical <0, the bar will be stable no matter where the block of mass my is placed on it Assuming that my d. and L are held fixed, what is the maximum block mass mu for which the bar will always be stable? In other words, what is the maximum block mass such that Fritical 0 Answer in terms of my, d, and L. View Available Hint(s) Submit Hint 1. Requirement of stability If zis calculated to be less than zero, the solution is unphysical (The bar does not extend there to support it) The minimum value that z can have is obviously zero. If m is less than the mass that would give critical =0 then the bar will be stable for any physical value of z ΜΕ ΑΣΦΑ A C Request Answer < 4 of 5. 4 of 5 = Review Constants ?
