The setup below is designed to test the bending properties of
a bome. A half Wheatstone bridge is used to measure the strain
absolom induced in thr bending of the bone.
a)

12. The setup below is designed to test the bending properties of a bone. A half Wheatstone bridge is used to measure the strain s induced in the bending of the bone. The resistance of the strain gages RG R when the strain is zero. (a) Derive the sensitivity Vsof the strain measurement in terms of V., R and G, where G is the gage factor of the material of the strain gages in use. (Refer to Problem 4 for the formula for the output voltage K, for a Wheatstong bridge. Also--G-8) AR (b) You now want to find a proper strain gauge to use for this test. You expect your strain at these locations to be 5%, or -oos. What should your gauge factor be in order to achieve a IV output with a 10V source, using the expression you derived in part (a? Ra R Ve (top) Ro (bottom) Ro
