Two blocks, connected by a rod of length 7, slide in frictionless grooves in a vertical plane as shown. Initially, the rod is stationary and vertical (0-0), and the spring of stiffness k is unstretched. Under the action of the constant force F, the rod angle increases. Assume that the mass of the rod and block B are both negligible. Using energy methods, find relationships for the following quantities as a function of the parameters provided: (a) work done by F when 0-45°, and (b) speed of block A of mass m when = 45°. A www.

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…
