Problem 6 (10 points): Suppose a certain accelerometer chip measures data in 20-bit two's complement format and stores it across three registers in the following manner: X19 X18 X17 X16 X15 X14 X13 0 X12 X11 X10 X9 X8 X7 X6 0 Register_1 Register_2 X5 X4 X3 X2 X1 X0 0 0 Register_3 where, X0 is the least significant bit and X19 is the sign bit. The accelerometer is set to output data within the range of -6g to +6g.

A. [4 points] What is the resolution of the accelerometer in terms of g (e. g., 0.43g, g/32, etc.)?

B. [6 points] If you configure your microcontroller to read only two of the three registers,

a. Which two registers should you choose?
b. "The range of acceleration that can be measured is now -4g to +4g": True or False?

c. If the speed of data transfer (in bits per second) from the accelerometer to µC is constant, the effective sampling rate will (circle one) (i) increase (ii) decrease (iii) remain the same

d. The effective signal-to-quantization noise ratio (SQNR) will (circle one) (i) increase (ii) decrease (iii) remain the same

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
