You are evaluating a variety of new materials for use in the femoral stem of a hip joint replacement. A. Draw the reduced sphere Diagrams of the crystal structures of materials
1. Simple cube.
2. FCC
B. Identify the crystal structure. For each structure.
C. Calculate the coordination number.
D. Derive the relation between r ( radius of sphere) and a ( length of cubic side) and determine the APF of each.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
