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.

The elastic region of a materials stress strain graph is shown below. Determine the Modulus of Elasticity from the graph data then select the correct modulus in the choices below.        20,000,000 psi     30,000,000 psi     40,000,000 psi     5,000,000 psi

Simulated Annealing How would Simulated Annealing perform if the temperature, T, is always equal or very close to 0, where we omit the termination test (except that we terminate the search when a goal node, either a local or global optimum, is met)? Please pick up one option from the following options and explain.(a) A random walk(b) Hill-Climbing(c) It would halt immediately(d) It would never halt

A random sample of 83 reconstructed clay vessels from the Turquoise Ridge archaeological site indicated the standard deviation of diameters to be approximately 5.5 cm. How many more such clay vessels must be found and reconstructed to be 95% sure that the sample mean of diameters is within 1 cm of the population mean of all such reconstructed clay vessels at this archaeological site?

In most cases a validation of the estimate is a sanity check' to ensure that the estimate is reasonable. What strategies and processes are used to conduct a validation of an estimate? Provide a brief explanation of each. (50-80 words)

As the tempering temperature of a heat-treated steel increases, the associated values of Brinell hardness also increases, while the values of tensile strength and yield strength decrease. True False   The correct definition of Dimensional Analysis is:     A procedure to find the yield point of a material when no definitive yield point can be determined graphically.     A procedure to calculate the Elastic Modulus.     A procedure to verify the size of a mass of material.     A methodical process of converting from one set of units to another set of units.

3. Microfluidic channels will need to be fabricated on a key micro-scale sensor used by aerospace industries. Before running machining tests and analyzing machined quality, preliminary efforts are needed to evaluate selected materials and factors affecting machining process¹. Three material candidates have been selected, including 422SS (stainless steel), IN718 (nickel alloy), and Ti64 (titanium alloy) with their measured tensile properties and equation of true stress-true strain relationship used listed below. Tref25°C. Specifically, three factors will need to be evaluated, including different materials, temperature, and size effect. Please calculate true stress values for true strain ranging between 0-3 for each case listed below.

The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer, independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000 wafers. Assume a 20% annual interest rate for holding cost calculations. a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the optimal order quantity? b.
