- A telescope aiming (star tracking)
mechanism - A backhoe bucket control mechanism
- A thermostat adjusting mechanism
- A computer printer head moving mechanism
- An XY plotter pen control mechanism
a.
To define:The following examples of telescope aimingcases study given in the problem.
Explanation of Solution
Given information:
The case study of the initial conditions is given that about a telescope aiming or star tracking mechanism.
Calculation:
A telescope aiming or star tracking mechanism that shows a path generation. A star goes along the sky with a
The working mechanism in the line diagram is shown below.
b.
To define: The following examples bucket control arrangement case study given in the problem.
Explanation of Solution
Given information:
The case study of the initial conditions is given that about a telescope aiming or star tracking mechanism.
Calculation:
This is motion generation mainly todigging a trench, say; the location and bucket alignment must becontrolled.
The working mechanism in the line diagram is shown below.
c.
To Define:The following example of thermostat adjusting mechanism case study given in the problem.
Explanation of Solution
This thermostat adjusting mechanism shows a Function generation.Here the output is a chosen function of input over input range.
The working mechanism in the line diagram is shown below.
d.
ToDefine:The following example of the computer printing head moving mechanism case study given in the problem.
Explanation of Solution
Here a moving mechanism of a computer printing head shows path generation and head to be point on a path.
The working mechanism in the line diagram is shown below.
e.
To find:The following examplesof XY plotter pen control mechanism cases study given in the problem.
Explanation of Solution
Here a control mechanism that having an xy plotter pen shows a Path generation and here a pen goes a straight line from point to point.
