Document Summary
Short answer questions - use the space provided for written answers. Closed book, closed notes, one hand-written formula sheet allowed: [24] a) show that for a cantilever beam with a rectangular cross-section in pure bending and a full. Wheatstone bridge the relationship between input and output voltages is. E in: determine the output voltage, eout, and the uncertainty. Input voltage, ein = 15. 0 volts (assume exact) Over: [12] a table of experimental data from the step response of a 1st order system is given below. Determine the time constant for the system and estimate the uncertainty in the time constant. 1. 50: [24pt] a dc permanent magnet motor develops 45. 2 in-lbf of torque when operated at an armature voltage of va=60 volts and a speed of 1035 rpm. The manufacturer claims that the motor has a stall torque of 8. 0 n-m when operated at an armature voltage of va=60 volts.
