An arm of the cylindrical robot which is driven by a direct-current motor needs a torque of 100 in-lbs. The DC motor has a torque constant of 3 in-lbs per ampere. How much current is needed to drive the robot arm at maximum load?
What will be an ideal response?
In DC motor, the torque is related to magnetic flux
and current I by,
Since is constant for permanent magnet motor, torque is proportional to armature current in steady state. The DC servomotor drives a mechanical load consisting of dynamic and static components,
J is the combined moment of inertia of the motor and load, is the static load due to friction and other forces in robotic system

Answer the following statement true (T) or false (F)
To improve crack detection in military aircraft, the Air Force combined ultrasonic inspection procedures with laser heating to identify fatigue cracks. Early detection of cracks may reduce repair costs by as much as $200,000 per year. If the savings start at the end of year 1 and increase by 3% each year through year 5, calculate the present worth of these savings at an interest rate of 10% per year.
