1. R Given: A 2.8 cm x 5.0 cm rectangular rod is stretched from its initial length of 0.4000 m to a length of 0.4005 m. • The modulus of elasticity of the rod material is 95.0 GPa (gigapascals). • Poisson's ratio of the rod material is 0.333. (a) To do: Calculate the axial stress in units of MPa. (6) To do: Calculate the transverse strain in units of microstrain. R (e) To do: A strain gage with a strain gage factor of 2.10 is glued 6+ to the rod before it is stretched, aligned with the direction of V V stretching. A quarter bridge Wheatstone bridge circuit is constructed, with the strain gage as resistor Rs. The strain gage is balanced before the rod is stretched. The bridge supply R. voltage is 7.50 V. Calculate the output voltage (in mV) of the bridge after the rod is stretched.
