Question
Chapter 4, Problem 1RQ
To determine
Identify the two basic types of overload relays.
Expert Solution & Answer
Explanation of Solution
Overload relays are used to protect the motor from overloading by sensing the current flow in the motor.
The two basic types of overload relays are as follows:
- Thermal overload relay
- Magnetic overload relay

In MATLAB write out a program to integrate the equations of motion of a rigid body. The inertia matrix is given by I = [125 0 0; 0 100 0; 0 0 75] which is a diagonal, where diag operator provides a matrix with given elements placed on its diagonal. Consider three cases where the body rotates 1 rad/sec about each principal axis. Integrate the resulting motion and study the angular rates and the resulting attitude (use any attitude coordinates). For each principal axis case, assume first that a pure spin about the principal axis is performed, and then repeat the simulation where a small 0.1 rad/sec motion is present about another principal axis. Discuss the stability of each motion. The code should produce a total of 6 simulations results when it is ran.
