2) Two objects with equal mass and equal and opposite velocity collide with each other. Find the relationship between angle of impact and absolute impulse experienced by each object. Note any angles that have special characteristics. This is an abstract problem where we will derive a general solution valid for any two masses, any two equal and opposite initial velocities and any angle of impact. You may assume the shape of the object plays no part in the outcome of the collision.

Question 2 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…

- Explain how each of these variables relate to environmental impact assessment and how they affect the concentration of a pollutant released by an action in the environment temporally or spatially:  time, source, receptor, convection, dispersion, reaction.For example: time ‐ time is the duration over which the impact assessment is modeled, and extends from 0 before the action (existing condition) to some time in the future after the action has occurred (impacted condition); time affects concentration for unsteady problems.

Analysis and Interpretation of vertical Ground Reaction Forces. In this study, a volunteer was asked to walk on two force platforms under two different conditions. Condition 1- Normal Walk (NW), condition 2 - walking over an obstacle (ObsW). The right limb was the one to step on platform 1 in both conditions. The force platforms were used to measure the vertical ground reaction forces on the right limb. Data was collected on Vicon (Nexus) software and the attached graphs ( mean NW/ObsW, Mean (+-)1SD NW/ObsW) were created. Analyse ,Interpret the graphs and make a conclusion of the result attached.
