APRAXIA OF SPEECH REFLECTS AN IMPAIRED CAPACITY TO PLAN OR PROGRAM SENSORIMOTOR COMMANDS NECESSARY FOR DIRECTING MOVEMENTS THAT RESULT IN PHONETICALLY AND PROSODICALLY NORMAL SPEECH.
=SPASTIC DYSARTHRIA IS A PERCEPTUALLY DISTINCT MOTOR SPEECH DISORDER (MSD) PRODUCED BY BILATERAL DAMAGE TO THE DIRECT AND INDIRECT ACTIVATION PATHWAYS OF THE CENTRAL NERVOUS SYSTEM (CNS).
=STROKES IN THE INTERNAL CAROTID AND MIDDLE AND POSTERIOR CEREBRAL ARTERY DISTRIBUTIONS, AND LESS FREQUENTLY IN THE ANTERIOR CEREBRAL ARTERY, CAN PRODUCE SPASTIC DYSARTHRIA.

Estimate the safety factor with respect to bending fatigue and with respect to surface fatigue for the worm gear reducer operation described in right-hand triple-threaded worm, with a 16:1 velocity ratio, p=0.25 in, , and . The worm is driven by a motor delivering hp. The worm is hardened steel and the gear is chill-cast bronze; Estimate the steady-state oil temperature if the ambient air temperature is 100 degrees F and the reducer is equipped with an integral fan on the end of the worm shaft.
The tooling on the dial assembly of figure shows a dial assembly. The dial is by -thick solid steel and is bolted to the top flange of the shaft. The shaft is over length and dia over length and is carried on tapered roller bearings All shaft fillet radii are . A motor drives the shaft through a reduction gearbox and a commercial bellows coupling. The maximum rated torque from the motor is and its stall torque is its rated torque. Find the maximum stress and angular deflection in the shaft under conditions of dial locked and motor at stall. and the figure imparts a timevarying torque to the dial that ranges from a peak of of the motor's rated torque (at the motor) to zero, times per dial revolution. If the motor speed is , find the worst-case stress-time and deflection-time functions for the shaft. Choose a shaft material to give a safety factor of at least against failure. Disregard the response of the system to the forced vibration.
